Patent abstract

An optical transmitter for generating a modulated optical signal for transmission over a fiber optic link to a remote receiver including a laser; an input coupled to the laser for directly amplitude modulating the laser with an analog RF signal to produce an output optical signal including an amplitude modulated information-containing component; and a phase modulator coupled to the output of the laser for reducing the distortion present in the received optical signal at the remote receiver.
