Unusual optical phenomena arise when light interacts with time-varying dielectric media. Here, relativistic propagation of a photoconductivity front in silicon is exploited to temporally stretch and time-reverse terahertz pulses.

We demonstrate broadband, frequency-tunable, phase-locked terahertz (THz) generation and detection based on difference frequency mixing of temporally and spectrally structured near-infrared (NIR) pulses. The pulses are prepared in a gas-filled hollow

Relativistically moving dielectric perturbations provide an exotic pathway for control over the spatiotemporal properties of light. We present our recent experimental results in applying this technique to the triggering and structuring of coherent te

We demonstrate experimentally a strategy for using relativistic moving dielectric fronts to trigger and affect the generation of coherent terahertz (THz) pulses. Our emission mechanism draws energy from the photoexcitation of built-in static Schottky

We demonstrate the trapping of a broadband THz pulse in a cavity with dynamic walls created faster than the cavity transit time. The trapping bandwidth and dwell time within the cavity, formed by patterned fs photoexcitation of reflective metallic re

Control over the spectral phase of a light pulse is a fundamental step toward arbitrary signal generation in a spectral band. For the terahertz spectral regime, pulse shaping holds the key for applications ranging from ultra-high speed wireless data

We demonstrate a frequency-tunable phase-locked terahertz (THz) source relying on nonlinear optical propagation of a femtosecond near-infrared pulse inside a gas-filled hollow-core photonic-crystal fiber (HC-PCF).
