Advanced Photonic Communication Systems

An ultrahigh-speed 8-b multiplexer (MUX) and demultiplexer (DMUX) chip set has been developed for the synchronous optical network (SONET) next-generation optical-fiber communication systems, which will require data bit rates of about 10 Gb/s. These ICs were designed using three novel concepts: a tree-type architecture giving reliable operation, a dynamic divider with a wide operating range, and a 50- Omega on-chip transmission line with high-speed pulse propagation. They were fabricated using a 0.5- mu m WN/sub x/-gate GaAs MESFET process. The DMUX and MUX operated at up to 10.4 and 11.4 GHz, respectively, both with an adequate phase margin of more than 230 degrees . >
