摘要

We experimentally demonstrate the C-band wavelength conversion using four-wave mixing in a 17-mm-long silicon-on-insulator waveguide pumped by a dispersed mode-locked femtosecond laser pulse.The idler can be observed with an incident average pump power lower than 4 dBm,and about 35 nm of conversion bandwidth from 1530 nm to 1565 nm js measured by using a 1550-nm pump wavelength.The pulse-pumped efficiency is demonstrated to be higher,by more than 22 dB,than the ew-pumped efficiency.The conversion efficiency variations with respect to the pump and signal powers are also investigated.
