Parametric Wavelength Conversion from the Conventional Near-Infrared Band to the Visible

The feasibility of distant wavelength conversion in photonic crystal fiber was explored. The one-pump parametric architecture was used to demonstrate translation from the conventional band (near 1550 nm) to the visible band (near 550 nm). Experimental results are reported, which demonstrate the conventional- to-visible conversion of single- and multiple-channel signals encoded in the non-return-to-zero format.
