| Abstract: | The wavelength conversion mechanism and the thresholding conversion characteristics of all-optical wavelength converter based on a laser diode are described by the gain saturation effect.The thresholding conversion characteristics of fiber grating external cavity laser diode is investigated.The experiment results show that the signal extinction ratio can be improved from 5dB to 30dB and intensity fluctuation can be suppressed to 0dB. |

| Keywords: | All-optical wavelength conversion External cavity laser diode Gain saturation Thresholding conversion |
