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.<>

用于光通信的ASIC芯片组
一种用于通过自由空间介质的1.3 Gbps光通信链路的发送/接收芯片组已在GaAs中实现。链路编码为Q=4脉冲位置调制(PPM),节省了激光器的功率需求。该芯片组为这种类型的应用提供了前所未有的发射器和接收器功能集成。
