We quantify the percent-level bias in dual-comb spectroscopy due to nonlinearities from the analog-to-digital conversion and demonstrate a compensation method
This invention is a new kind of laser radar (LIDAR) that uses two special lasers called femtosecond fiber lasers. One laser sends out a signal, and the other helps detect the signal that bounces back from a target. It combines two types of measurements—time-of-flight and interferometry—to measure

This invention introduces a dual comb spectroscopy system that enhances optical measurement accuracy. It uses two optical frequency combs to analyze light absorption and emission with high precision. The system improves data collection speed and reduces errors in spectral analysis. It is designed to
The invention is an optical frequency comb sub-system that utilizes nano-scale photonic waveguides made of aluminum gallium arsenide (AlGaAs) to perform the nonlinear frequency conversion required to realize f-to-2f self-referencing. Thanks to the high optical nonlinearities, this task can be
