We have studied experimentally spectral characteristics of a multi-mode vertical-cavity surface-emitting laser that is subject to optical feedback. Appropriate alignment of the feedback mirror can suppress higher-order modes and significantly decrease the spectral linewidth of the laser.
Effect of the alignment of optical feedback on a multi-transverse-mode vertical-cavity surface-emitting laser is investigated experimentally. Enhancement of the fundamental mode or higher-order mode is achieved by adjusting the alignment of the feedback mirror. When the strength of feedback is stron
