Low-loss dispersive components are critical to photonic time-stretch analog-to-digital converters (TS-ADCs) for attaining high resolutions. Chirped fiber-Bragg gratings (CFBGs) provide low losses plus high nonlinear thresholds but introduce time-warp

We report the demonstration of a time-stretch photonic analog-to-digital conversion (ADC) system with a stretch ratio of . By stretching a 10-GHz modulation envelope to 242 MHz via optical dispersion, we demonstrated, for the first time, an ADC resol

A photonic ultra-wideband (UWB) impulse transmitter based on chirped heterodyning is demonstrated. It uses no high-speed electronics or optical modulators. Multiple data formats including high-order pulse-position modulation are implementable, as is

Using multiple signal beams and controlling their relative phases, we demonstrate angular multiplexing of phase-sensitive holographic gratings in a photorefractive crystal. Interference between diffracted signal beams determines total diffracted inte

The Faraday photorefractive effect is demonstrated by combining photorefractive two-beam coupling with Faraday rotation in Cd1–xMnxTe, a diluted magnetic semiconductor. Two-wave mixing is monitored as a function of incident-beam polarization and ma

Matched filtering of megahertz-bandwidth signals by use of holograms recorded in a photorefractive crystal is demonstrated. Holographic recording of rapidly varying signals has heretofore been hampered by the relatively slow response of photorefracti
