Abstract
The present invention relates to an optical transmitter that includes an optical modulator configured to modulate an optical signal with a digital data stream, and a heater configured to apply heat to the optical modulator. The optical transmitter also includes an optical receiver configured to receive the modulated optical signal and to convert the modulated optical signal into a received digital data stream. A circuit is configured to compute bit errors in the received digital data stream by comparing the received digital data stream with the digital data stream, and control the heater based on the computed bit errors.
