Definitions

  • This invention relates to an apparatus for receiving optical signal, especially an antenna.
  • electromagnetic wave has been a major means of wireless communication. As the users of wireless communication multiply, the demand for a new mode of communication emerges. Light being a spectrum of electromagnetic wave is a potential mode of communication to address the demand.
  • US 4,092,061 A discloses a side-coupling of light for an optical fibre.
  • Light is coupled into and out of an optical fibre from the side by providing an acute angular cut along the end of the optical fibre and locating a light source adjacent the side of the optica! fibre opposite the inner-facing surface of the cut such that light reflects from the cut surface substantially parallel to the optica! axis of the optica! fibre.
  • the outer surface of the cut is rendered reflective.
  • the curved optical fibre cladding material between the side located light source or detector and the inner surface of the cut end of the optical fibre acts as a lens to collimate the light from the light source.
  • an apparatus for receiving optical signal which comprises: an optical fibre, a portion of which is covered; at least one strip of nanomaterial encircling the uncovered portion of said fibre; and a photodetector coupled to one end of said fibre, for converting optical signal to electric signal; whereby during use, an optica! signa! of at least one wavelength is laterally excited onto said nanomaterial-encircled portion, such that said nanomaterial will scatter the signal into said fibre through which the scattered signal will be guided to said photodetector.
  • the apparatus also comprises a computer connected to said photodetector, for storing and processing the electric signal.
  • the nanomateriai is zinc oxide.
  • said strip of nanomaterial encircles the uncovered portion in a helical manner.
  • the apparatus aiso comprises an opaque seal which covers the other end of said fibre, for stopping at least one optical signal from entering said fibre through said other end.
  • Fig. 1 is a schematic diagram of the apparatus for receiving optica! signal, according to the invention.
  • the apparatus comprises: an optical fibre 1 , e.g. plastic optical fibre, a portion 2 of which is covered; a strip of nanomateriai 3, e.g. zinc oxide, which encircles the uncovered portion 4 of the fibre in a helicai manner; a photodetector 5 coupled to one end of the fibre 1 , for converting optical signal to electric signal; a computer 6 connected to the photodetector 5, for storing and processing the electric signal; and an opaque seal 7 which covers the other end of the fibre 1 for stopping optical signals 8 from entering said fibre 1 through said other end.
  • optical signals each of a separate wavelength, also known as channel, is laterally excited onto the nanomateria!-encircled portion 4.
  • the nanomateriai 3 will scatter the signal into said fibre 1 through which the scattered signal will be guided to said photodetector 5.
