150~(+) Channel Ultra-DWDM Source with N×10 GHz Spacing Utilizing Longitudinal Mode Slicing of Supercontinuum

摘要

We report a novel multiple wavelength continuous wave (CW) source using fiber-based supercontinuum (SC) and longitudinal mode slicing of its spectrum. From a SC with 140 nm spectral region and 10 GHz repetition rate, we slice 150 CW channels with precise N×10 GHz spectral spacing, ±0.5 dB uniformity over 48 nm, and >12 dB peak-to-trough contrast. Less than 7 dB/Hz relative intensity noise (RIN) degradation with respect to the source laser is observed.
