Abstract :
A transmitter/receiver chipset has been implemented in GaAs for a 1.3 Gbps optical communications link through free space media. The link encoding is Q=4 pulse position modulation (PPM), which economizes the power requirement of the lasers. The chipset offers an unprecedented integration of transmitter and receiver functions for this type of application.<>
