Ultrafast All-Optical Complete Phase Modulation at Near-Infrared Wavelengths in an Epsilon-Near-Zero Material by Femtosecond Frequency-Domain Interference
Abstract
Abstract Ultrafast optical phase modulation plays a key role in modern high-speed optical processing and integrated photonic devices. However, most existing transient phase modulation strategies are implemented through indirect phase measurements. Although several works on direct estimation of phase change in microstructured semiconductors via time-resolved interferometers have been reported, the small modulation depth (
