| 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. |
