Abstract

By the method of amplitude-phase decorrelation, intensity noise from a distributed feedback semiconductor laser is passively reduced up to 14.5 dB below its intrinsic level. At high laser power, reduction to 1.3 dB above the photon shot noise level is observed. The results agree with a simple model incorporating a power-independent source of phase noise in the laser rate equations.
