Abstract :
Current research on next generation Wavelength Division Multiplexed (WDM) all optical networks has identified the need for arrays of laser driver circuits and arrays of receivers, clock recovery, and decision circuits. This paper reports on the development of two AlGaAs-GaAs HBT-based circuits: an eight-channel laser driver array and four-channel signal regeneration array including the limiting amplifier, clock recovery, and decision functions one intended for operation at 155 Mb/s. Subcircuits of the clock recovery array have been verified as suitable for use up to 2.488 Gb/s
