  • Abstract
    An optical FSK receiver based on a multielectrode DFB laser is reported. The device, biassed just below threshold, acts as a tunable filter, FSK discriminator and photodetector. Using two-electrode DFB laser for the transmitter and the receiver a FSK transmission up to 1.5 Gbit/s with -20 dBm sensitivities for 10-9 BER over 40 km single mode optical fibre was observed.
