Abstract :
Data-induced polarisation switching is a simple yet powerful technique to solve the polarisation problem in optical FSK heterodyne systems. The authors achieve a polarisation- and pattern-independent sensitivity of -53.5 dBm for a 140 Mbit/s FSK receiver. The response time to polarisation changes is estimated as 100 ns.
