We experimentally demonstrate a novel multiwavelength continuous wave (CW) optical source with precise 25-GHz spacing based on the longitudinal mode-carving of a supercontinuum (SC) spectrum. The CW light was modulated with a 10-Gb/s non-return zero (NRZ) format. The experimental results show that the multiwavelength CW optical source is promising for dense wavelength division multiplexing (DWDM) systems.
