Nonlinear Spatio-Temporal Processing of Femtosecond Pulses for Ultrahigh Bandwidth Communication

Abstract

We emphasize developing high speed and high efficiency parallel to serial multiplexers and serial to parallel demultiplexers, the two most critical challenges for current technology to meet the needs of ultra high bandwidth communication applications. In the following we describe research on nonlinear spatio temporal processors using cascaded second order nonlinearity to perform (1) Spatial temporal wave mixing for space to time conversion, and (2) Instantaneous time reversal and phase conjugation of ultrafast waveforms. In addition, we will also report our study on a (3) Femtosecond single shot pulse imaging system that uses transverse time delay pulse cross correlation.
