375 THz Parametric Translation of Modulated Signal from 1550nm to Visible Band

Record parametric frequency-translation of NRZ-modulated signal over 375THz is demonstrated using silica-PCF. The 1550-nm band is mapped to visible 500-nm spectral window, proving the feasibility of all-fiber universal band translator. Both single-channel and WDM architectures are constructed and demonstrated experimentally.
