Novel FM Microwave Fiber-Optic Link for Antenna Remoting and Phased Arrays

摘要

In this final report, we report the first analysis and experimental demonstration of tunable microwave/millimeter wave signal generation in two section gain coupled DFB lasers. Continuous tuning from 20 to 64 GHz was directly observed and characterized both in the electrical and optical domain. The mechanism of microwave generation in two section gain coupled DFB lasers is different from that of two section index coupled DFB lasers previously reported. As a result, gain coupling can lead to simultaneous large modulation indexes and high frequencies in two section DFB lasers.
