1000 channel optical carrier generation from a single supercontinuum source with 12.5 GHz channel spacing for DWDM and frequency standards

摘要

We have generated over 1000 channel optical carriers with a 12.5 GHz spacing and high SNR from a single supercontinuum source. It was confirmed that 600-700 modes have sufficient SNR for achieve Q-factors of more than 18 dB for wavelength range from 1512 nm to 1580 nm. The channel spacing is strictly determined by the microwave mode-locking frequency having a Hz accuracy. The generated optical carriers can be applied to DWDM systems and optical frequency standards.
