Abstract:
1. A parallel light emitting device—photosensitive device module for coupling to a multichannel optical transmission medium with a plurality of parallel optical fibers arrayed with a defined pitch, comprising: a bench; a plurality of lightpaths including a narrow width region, a curving width enlarging region and a wide width region and being made on the bench; a transmitting portion including a plurality of light emitting devices or an array of light emitting devices mounted at ends of the wide width region of the lightpaths for yielding transmitting light signals; a selective reflection device mounted upon the wide width region of the lightpaths for reflecting receiving light signals propagating in the parallel optical fibers but allowing the transmitting light signals for the light emitting devices to pass through; and a receiving portion including a plurality of photodiodes or a photodiode array mounted above the wide width region of the lightpaths for sensing the reflected receiving signals.
