V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a microfiber device 'in particular, refers to a technology for connecting, disposing, and fine-tuning components such as a light processing element, a collimator, and a connecting tube constituting a microfiber optical device. . — The previous technology. In terms of traditional technology, the most common way to make micro-fiber devices is to first prepare two separate optical collimators and insert a light between them. Ξ ::: ί 成; The processing element may be a component with predetermined functions, for example, it may be a WDM filter (iS〇lat〇r C〇re), PM COrabiner double pass magnet Core (ClrCUlat〇 " ㈣), by which micro-fiber devices such as ell devices, fiber isolators in-line, fiber PM Comb, and fiber optic passthroughs are used; collimators and light processing components The combination of oxygen resin) technology (welding) (such as: soldering) or bonding (such as: made by the ring); for example: the shell of the aforementioned collimator can be gold directly to the sister and then The light processing element is transmitted through epoxy resin or solder, and the second group) Γ = the aforementioned first or second collimator (which constitutes a so-called point-bonding or welding coil, and will be attached to the fiber collimator) Through the sub-body through the system; It is possible to complete the micro fiber device

1235257 V. Description of the invention (2) The above-mentioned traditional micro-fiber device assembly method is in the manufacture of the first fiber component, but after all, the aforementioned micro = widely used technology, the components of the county ’s Luliu-shao pa fiber-coating are thin · 夂 a P relies on the author's skilled technology and skills, and the accuracy of the finished product of 隹 — 土 牛 σ is different, and the yield is unspeakable .: For those who are not only skilled, it is not easy to find; In terms of # $ ί important 疋, the light processing element system is directly invited to collimate directly, # the light path of the element…, will definitely produce the light path; :: = light treatment, such as: when the adhesive is deteriorated) & quot Use welding method

Stress must be applied to the components (commonly known as, 扳, "), and the finished products composed of quasi-technologies usually face high temperature dependent losses (teinperature dependent 10ss) and intervention losses ("Μ g 1 〇ss) and other serious optical fiber signal transmission loss defects; F, the development of traditional micro-fiber device design, there is no considerable degree of bottlenecks; In addition, the current manufacturing of micro-fiber devices in addition to the aforementioned traditional technology, more like According to the US patent No. 6 1 85354, the technology for manufacturing optical fiber wavelength division multiple device (WDM) device is still using a double fiber collimator and a single fiber collimator; in this dual fiber collimator In the first step, a wavelength division multiplexing filter is directly bonded and fixed to a first microlens (GRIN lens) with a heat-treated epoxy resin, and then the subgroup is embedded in a glass tube. And use the heat-treated epoxy resin to fix it; then, the double fiber optic lead (pigtai 丨) is aligned with the lowest reflection intervention loss to the subassembly 'and connected to the glass with a second glass tube Subgroup

1235257

In this way, the dual-fiber collimator can be formed; the shovel two T: 1 side 'in the setting constituting the M single-fiber collimator', the second micro one: glass its Φ and single-fiber lead (Pigtai 1) system Be placed in the second glass officer, aim at the lowest value of private * M ® q & transfer wheel alignment loss to the dual fiber collimator, = use, heat-treated epoxy to fix it; finally, use the minimum Transmission medium: The loss is aligned with the dual-fiber collimator and the single-fiber collimator, and it is connected to the first glass tube and the third glass office with 2 processed fluorene resin. Although this technical method is simple, however, It is worth noting that 70 of the light treatments are still directly bonded to the first microlens with epoxy glue directly in the optical path. This design not only fails to provide the best reflection, focal length and alignment, but also has obvious transmission intervention. The problem of loss. As mentioned above, as far as the wave centering technology is concerned, the eyepiece is directly mounted on the micro-type, which requires the operator to cooperate with the alignment filter and the micro-transparent coating on the micro-lens (GRIN flows into the optical path, which is at the same time. (U.S. Patent No. 6,185 GRIN lens and the design in the optical path will regret that it cannot withstand high power division multiplexing filters. The industry's widest lens (GRIN Le uses a microscope and a mirror (GRIN lens lens ) Around them, No. 347), between the ring filters, there are problems such as epoxy resin change, so the general use of purple) on ns), and, together, because of the infiltration of gas resin into the system The system uses one wave to divide the wave; the other line uses ultraviolet light to prevent the aforementioned system from being created with an epoxy tree light path and a multiplexer is installed to divide the multiplex filter. In a technical state, the line glue is epoxy. The lack of the patent of resin in this micro-transparent month is not like the shuttle
