Paper Abstract

The design, fabrication, and testing of a new monolithic transmitter for fiber optic interconnects is described. The transmitter is comprised of a surface-emitting AlGaAs/GaAs light-emitting diode (LED) integrated with a bipolar transistor driver circuit configured as a differential-pair current switch. Two approaches are being are being pursued: 1. the LED is integrated with a silicon-based bipolar transistor driver circuit using a novel heteroepitaxy process based on a combined chemical-vapor deposition Iliquid-phase epitaxy technique, and 2. the LED is integrated with a GaAs-based bipolar transistor driver circuit using selective liquid-phase epitaxy and diffusion processes. Transmitter components have demonstrated sub-nanosecond rise-times.
