Abstract
Semiconductor lasers with microring resonators were demonstrated as frequency-selective elements. Single frequency mode operation was obtained with side-mode rejection. It was found that side longitudinal-mode suppression can be enhanced for better single-mode lasing purity with gain control in the ring resonator separate from that in the active laser medium.
