Abstract
Disclosed are an optical waveguide and a bi-directional light transceiver, in which a wavelength selective filer is provided in the core of the optical waveguide to divide bi-directional signals, so that manual alignment of optical components are easily achieved and thus a small bi-directional light transceiver is realized and transmission/reception efficiency of light is enhanced.
Claims20
An optical waveguide comprising:
- a core to transmit light;
- a cladding to constrain light inside the core through total internal reflection while surrounding the core;
- and
- a wavelength selective filter accommodated in the core to divide bi-directional signals.

A bi-directional optical transceiver comprising:
- an optical waveguide including a core to transmit light, a cladding to constrain light inside the core through total internal reflection while surrounding the core, a wavelength selective filter accommodated in the core to transmit or block signals travelling in opposite directions;
- is a light generation unit to output light to the optical waveguide;
- and
- a light detection unit to detect light from the optical waveguide.
