Paper Abstract

We construct a passive grating-based wavelength-division (de)multiplexer (MUX/DMUX) for single-mode-fiber networks. The MUX/DMUX has almost identical bi-directional filtering characteristics on optical signals at wavelengths around 1550 nm. With total insertion loss less than 3 dB and an enlarged passing band of each channel, the encapsulated device exhibits very stable performance under temperature variation and is immune from mechanical vibration. The insertion loss of this device changes about 1 dB at temperatures from 25 degree(s)C to 60 degree(s)C, while the enter wavelength of each channel drifts about 8.3 X 10-4 nm/(nm(DOT) degree(s)C). Better results are expected with further optimization on the design. The device successfully demultiplexes 231 -1 PRBS signals up to 3.5 Gb/s per channel in an emulated amplifier-free local- area networks (LAN's) and metropolitan-area networks transmission. It is plausible the cost-effective MUX/DEMUX is an excellent candidate to meet 10 Gb/s all-optical multi- wavelength short-link applications.
