The investigation majorly explored self mode-locking of self pulse. When the gain fiber was disturbed, the phenomenon of SML was observed in a yetterbium-doped ring cavity configuration. The system can produce a laser pulse width smaller than

In this dissertation, we demonstrate a direct method to observe higher-order whispering-gallery modes in vertical cavity surface emitting lasers (VCSELs) at room temperature. We show that suppression of lower-order cavity modes can be achieve
