Latest Patents

Walmsley's latest patents include "Pulse measurement using frequency shifting techniques - Amplitude and phase relative to an interferometrically established phase of ultrashort replica pulses." This invention utilizes spectral phase interferometry for direct electric field reconstruction by frequency shifting chirp replica pulses of an optical pulse to be measured. The replicas of the pulses, relatively delayed in time, are generated by an interferometer. Another notable patent is "Temporal measurements of ultrashort far infrared electromagnetic pulses - Dithered-edge sampling (DES)." This technique enables ultra-wideband measurement of terahertz pulses using photoconductive antennas. The terahertz pulse is sampled by first passing it through a triggered photoconductive attenuator, whose fast attenuation edge is dithered in time. A slow photoconductive receiver then measures the component of the terahertz electric field that is modulated at the dither frequency.
