Ultrafast Optical Wavelength Shuffling Based on Nonlinear Photonic Crystals.

摘要

At the time of this proposal we had developed the theoretical foundation for analyzing 2D periodic second order nonlinearities, from which we developed demonstration of simultaneous optical wavelength interchange I. shown that a properly designed 2-D quadratic nonlinear lattice can be used to produce a simultaneous, one-step, interchange of data between two carrier wavelengths XPj(caret)(caret)(caret) (Fig. 1). The two DFG processes essentially 'diffract' (caret) the Interconverted signals from the unconverted ones, providing spatial segregation to eliminate coherent in band cross talk. Subsequent to this, we presented the first experimental demonstration of simultaneous optical wavelength interchange 2,3. The nonlinear lattice, fabricated in LlNbO3, was designed to interchange the wavelengths 1535 ran and 1555 ran a theoretical was In that paper, Figure 1. Schematic representation of simultaneous wavelength interchange in 2D periodically poled LiNbO2.
