Abstract

A two-section traveling-wave semiconductor laser amplifier can be utilized as a time-division demultiplexer or channel selector in all-optical networks. Light injected into the amplifier causes changes in the carrier density, which manifests itself as a change in the amplifier electrode voltages that can be processed to obtain the original data signal. Numerical analysis shows that by suitable choice of the electrode bias currents responsitivity and speed are optimized while system transparency is maintained. With optimal device design, demultiplexing speeds of the order of several gigabits per second are feasible.
