Multimillijoule coherent terahertz bursts from picosecond laser-irradiated metal foils [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Terahertz (THz) radiation, with frequencies spanning from 0.1 to 10 THz, has long been the most underdeveloped frequency band in electromagnetic waves, mainly due to the dearth of available high-power THz sources.

Ultra Fast Nonlinear Optical Tuning of Photonic Crystal Cavities [PDF]
, 2006 We demonstrate fast (up to 20 GHz), low power (5 $\mu W$) modulation of photonic crystal (PC) cavities in GaAs containing InAs quantum dots. Rapid modulation through blue-shifting of the cavity resonance is achieved via free carrier injection by an above-
