Abstract
We demonstrate a high-power, multi-wavelength, short pulse source at 10 Gb/ s based on spectral slicing of supercontinuum (SC) generated in short fiber s, We show that short fiber SC can be used for dense wavelength division mu ltiplexing applications because of its >7.9 dBm/nm power spectral density, 140 nm spectral bandwidth, and +/-0.5 dB spectral uniformity over 40 nm. Pu lse carving up to 60 nm away from the pump wavelength and CW generation by longitudinal mode carving indicates that the coherence of the SC is maintai ned. By using high nonlinearity fibers, the spectral bandwidth is increased to 250 nm, which can accommodate >600 wavelength channels with 50 GHz chan nel spacing and >6 Tb/s aggregate data rate. We also calculate the coherenc e degradation due to amplification of incoherent energy during the SC gener ation. Theoretical results show that the SC generation in short fibers has 13 dB higher signal-to-noise ratio (SNR) compared to the SC generated in lo ng fiber.
