Please refer to Fig. 1-Fig. 3, among them, Fig. 1 is the structure diagram of an embodiment of the optical connection device of the present application, Fig. 2 is the exploded diagram of the optical connection device in Fig. 1, Fig. 3 is the optical connection device in Fig. 2 A cross-sectional view of an embodiment of a coupling. In this embodiment, the optical connection device 10 includes: a first connector 11 , a second connector 12 and an optical coupling member 13 .

Among them, the optical connection device 10 in this application is specifically aimed at the right-angle coupling requirements of the light emitted from the surface of the circuit board, and proposes an embedded or surface-mounted connection device capable of deflecting light, including integrated collimation, Reflective parts and optical connection parts.

It should be noted that, in this embodiment, the above-mentioned "integrated collimation and reflection components" are specifically optical coupling components 13, including lens arrays, reflective slopes, guiding structures, etc., to achieve collimation, reflection, and convergence of divergent light rays. . The above-mentioned "optical connection component" is a component with optical connection and optical transmission functions, specifically, it can be a connector with an optical transmission medium, or a structural member with a light emitting/receiving device, that is, the first connector 11 and the second connector 12.

Among them, light rays usually diverge during transmission, that is, two light rays that are initially adjacent will become farther and farther apart after propagation. In general, collimation is to keep the light rays parallel.

Specifically, the first connector 11 is correspondingly connected to the external first light guide medium 21, for example, a plurality of optical fibers arranged side by side, and one end of the plurality of optical fibers near the optical coupling member 13 is specifically embedded in the first connector 11 , so as to fix and bundle a plurality of optical fibers by the first connector 11 . In other embodiments, the first light-guiding medium 21 can also be an optical waveguide packaged with multiple core layers, and the optical waveguide is embedded in a corresponding groove formed by the first connector 11 so as to be compatible with the first optical waveguide. The connector 11 realizes the connection.

Similarly, the second connector 12 is correspondingly connected to the external second light guide medium 22, such as a plurality of optical fibers arranged side by side, or an optical waveguide packaged with multiple core layers, so as to connect the second guide medium 22 through the second connector 12. The optical medium 22 is fixed and bundled.

Further, the optical coupling member 13 includes a first side 1301, a second side 1302 and a third side 1303, and the first side 1301 is perpendicular to the second side 1302, and the third side 1303 is connected to the first side 1301 and the second side 1302 The angle between them is 45°.

Still further, a first plano-convex lens 131 is formed on the first side 1301 of the optical coupling element 13, and the first connector 11 is specifically connected to the optical coupling element 13 corresponding to the first side 1301, so that the first The extension direction of the light guide medium 21 corresponds to the first plano-convex lens 131 being perpendicular to the first side 1301, that is, the first light guide medium 21 and the first plano-convex lens 131 are arranged at intervals, and the first plano-convex lens 131 is located on the first light guide medium 21 in the direction of extension.

And the second side surface 1302 of the optical coupling element 13 is formed with a second plano-convex lens 132, and the second connector 12 is specifically connected to the optical coupling element 13 corresponding to the second side surface 1302, so that the extension direction of the second light guide medium 22 Correspondingly, the second plano-convex lens 132 is perpendicular to the second side 1302 , that is, the second light-guiding medium 22 and the second plano-convex lens 132 are spaced apart, and the second plano-convex lens 132 is located in the extending direction of the second light-guiding medium 22 .

Wherein, when the light transmitted by the first light guide medium 21 emits light to the optical coupling element 13, the light can enter the interior of the optical coupling element 13 from the outside of the first plano-convex lens 131, so that the first plano-convex lens 131 can collimate After straightening and converging, they are reflected on the third side surface 1303 of the optical coupling member 13 , and then emitted from the outside of the second plano-convex lens 132 to respectively enter the second light guide medium 22 for transmission.

It can be understood that the number of optical fibers corresponding to the first light guide medium 21 may be multiple, and the number of optical fibers corresponding to the first plano-convex lens 131, the second plano-convex lens 132 and the second light guide medium 22 are all corresponding to Multiple, and the number of the four are the same, and correspond to each other, so that the light emitted by the first light guide medium 21 and incident into the optical coupling element 13 can be collimated, reflected, and converged, and then correspond to into the second light-guiding medium 22 and continue to be transmitted by the second light-guiding medium 22 . Wherein each group of first light guide medium 21, first plano-convex lens 131, second plano-convex lens 132 and second light guide medium 22 corresponding to each other corresponds to an optical channel, and then an optical interconnection circuit logic can be realized. The optical path connection is completed, and the corresponding light can realize low-loss 90° reflection and transmission based on each optical channel.

In another embodiment, the number of the first plano-convex lens 131 and the number of the second plano-convex lens 132 can also be the same, and is greater than the number of optical fibers corresponding to the first light-guiding medium 21, while the number of optical fibers corresponding to the second light-guiding medium 22 includes The number is equal to the number of optical fibers included in the first light-guiding medium 21, so that the optical coupling 13 and The first plano-convex lens 131 and the second plano-convex lens 132 are optically interconnected, thereby effectively widening the scope of application of the first plano-convex lens 131 and the second plano-convex lens 132 .

In the above manner, because the first light guide medium 21 is specifically connected to the optical coupler 13 through the first connector 11, and the second light guide medium 22 is connected to the optical coupler 13 through the second connector 12, so as to be able to Subsequently, the connector and the optical coupling member 13 are disassembled flexibly, so that the connector and the waveguide can be reworked, maintained and upgraded more conveniently. And through the corresponding arrangement of the first side 1301, the second side 1302 and the third side 1303 of the optical coupling member 13 and the first light guide medium 21 and the second light guide medium 22, the 90° reflection and transmission of the corresponding light can be realized, which is relatively The loss of light is also smaller compared to bending optical fibers and transmitting light in free space. In addition, the optical connection device 10 can also be embedded in a corresponding circuit board to improve the integration of the circuit board, and the structures of the first connector 11 and the second connector 12 are relatively simpler and easier to form and manufacture. , which also effectively reduces the manufacturing cost of the optical connection device 10 .

Optionally, the refractive index of the optical coupling element 13 is greater than √2, so that total reflection can occur when the light incident from the outside of the first plano-convex lens 131 to the inside of the optical coupling is projected onto the third side 1303 of the optical coupling element 13, Furthermore, it can exit from the outside of the second plano-convex lens 132 to enter the second light guide medium 22 for transmission, thereby effectively reducing light loss.

It should be noted that the full name of the total reflection is total internal reflection, that is, when light enters a medium with a low refractive index from a high refractive index, the refracted light will disappear when the incident angle is greater than a certain critical angle, and all incident light will be reflected without reflection. into low-refractive-index substances.

It can be understood that, as shown in FIG. 4, FIG. 4 is a schematic diagram of light reflection, in which the first light guide medium 21 is used as a light emitting element, and the second light guide medium 22 is a light receiving element, and correspondingly realizes the collimation of light The refractive index of the optical coupling member 13 with functions of reflection and converging is n ₁ (n ₁ is any reasonable positive number), and the third side 1303 of the optical coupling member 13 is away from the other side medium of the first light guide medium 21 Taking the refractive index of n ₂ as an example, it can be seen that when the refractive index of the optical coupling element 13 satisfies n ₁ >n ₂ /sinθ ₁ , due to the principle of total reflection, the third side 1303 can make the lens from one end, that is, the second Light entering the first plano-convex lens 131 is reflected to the other end lens, that is, the second plano-convex lens 132 to exit.

Wherein, the θ ₁ is the incident angle of the light, and the angle between the reflective slope and the light, that is, the incident angle θ ₁ is generally 45°, which can be adjusted according to the specific use scene, and n ₂ is usually the refractive index of the air, The value can be 1.

It can be seen that, when the refractive index of the optical coupling element 13 satisfies n ₁ >1/sin45°, that is, n ₁ >√2, the light entering the optical coupling element 13 can be fully emitted at the third side 1303 .
