Abstract :
We propose a simple optical return to zero quadrature amplitude modulation (RZ-QAM) transmitter with Auto Bias Control (ABC) circuit. This transmitter is pulse carver free and offers electronic pre-compensation for chromatic dispersion (CD). Measured penalty induced by ABC was less than 0.2 dB, with and without CD pre-compensation.
