Bidirectional Fibre Optical Transmission using a Multiple Quantum Well (MQW) Modulator/Detector.
01 January 1986
We demonstrate a simple architecture for bidirectional optical fiber transmission which uses an MQW device as both modular and photodetector. We achieved transmission of 50 Mbit/sec and 600 Mbit/sec in the two directions over one 3.34 km long single-mode fiber at 860 nm wavelength. Coherent Rayleigh interference was found to be a limiting factor in single-source bidirectional systems.
