Abstract :
We propose an RZ-pulse wavelength converter which has a very simple device structure. Ultrafast wavelength conversion at an extremely low input power is demonstrated at 10-40 GHz repetition rates. By using a new simple wavelength converter (DISC), we have demonstrated efficient ultrafast wavelength conversion of 10.5 to 42 GHz pulses from 1548 to 1560 nm
