Patent ID: 7486708

Claim:
A method of stabilizing an output optical power from a laser source against drifts induced by at least one of temperature and aging, said output optical power including a target optical modulation amplitude (OMA target ) around a target average value (P target ), the method including the steps of: applying to said laser source selectively variable bias (I B ) and modulation (I M ) currents, and controlling said bias (I B ) and modulation (I M ) currents by: detecting an error between an actual average output optical power (P 2 ) from the laser source and said target average value (P target ), comparing said error against a given error threshold (ΔP), and when said error reaches said threshold (ΔP), adjusting said bias (I B ) and modulation (I M ) currents to bring the output optical power from said laser source back to said target average value (P target ) and said target optical modulation amplitude (OMA target ) around said target average value (P target ).
