Patent
CA 2313566
A device including a fiber/waveguide and a optical device (PD, LD or so). The end of an optical fiber or a light waveguide is cut slantingly. A transparent resin of a refractive index akin to the fiber/waveguide encloses the fiber/waveguide, the optical device and a space between them. The slanting end cutting and the transparent resin cooperate with each other to annihilate the reflection, returning light perfectly without reducing the coupling coefficient.
