Abstract

This paper presents frequency stabilization of intermodal oscillations observed in long optical cavity laser diodes. A 2170-μm-long optical cavity for a 1.5-μm laser experiences intermodal oscillation of /spl ap/19.3 GHz. This optical oscillation is stabilized using electrical injection locking process by modulating the gain section. A significant improvement in frequency stability and phase-noise reduction is observed. Performance of the injection-locked intermodal oscillation is compared to the mode-locking experimental results in terms of modulation power and FM noise degradation level.
