| Abstract: | Bistable characteristics of a grating tuned external cavity semiconductor laser (ECLD) with a strong external feedback have been studied.Starting from the derived explicit analytical expression of output power at the jump points of the hysteresis loops on power versus frequency curve.Then,the variation of magnitude of the power jumps of hysteresis loop with several vital parameters of the ECLD has been analysed. |
