Abstract :
We report the design, fabrication, and the characterization of a variable bit-rate receiver designed for wavelength-division multiplexing and wavelength division multiple access (WDM/WDMA) applications. The performances of these receivers can be optimized for bit-rates ranging from 300-1500 Mb/s. The tunability of the receiver bandwidth is achieved through adjusting the gate bias of a microFET used as an active feedback resistor in the transimpedance amplifier.
