ABSTRACT:
An injection-locked semiconductor laser process that improves the modulation bandwidth and reduces the broadband noise of an injection-locked semiconductor laser. Injection locking of a semiconductor laser can significantly improve its broadband modulation characteristics. By adjusting the frequency offset between the master laser and the slave laser, improved modulation bandwidth of the modulation response can be emphasized. The intrinsic modulation bandwidths can be enhanced above the theoretical limit for the free-running laser. The improved modulation characteristics are accompanied by reduced broadband relative intensity noise.
