In-line optical subtraction using a differential Faraday rotation spectrometer for 15NO/14NO isotopic analysis
Eric J. Zhang, Daniel M. Sigman, Gerard Wysocki
We present a dual-modulation Faraday rotation spectrometer with in-line optical subtraction for differential measurement of nitric oxide (NO) isotopologues. In-situ sample referenc…
Terahertz hyperspectral imaging with dual chip-scale combs
Lukasz A. Sterczewski, Jonas Westberg, Yang Yang +4
Hyperspectral imaging is a technique that allows for the creation of multi-color images. At terahertz wavelengths, it has emerged as a prominent tool for a number of applications,…
Mid-infrared dual-comb spectroscopy with low drive-power on-chip sources
Lukasz A. Sterczewski, Jonas Westberg, Mahmood Bagheri +9
Two semiconductor optical frequency combs consuming less than 1 W of electrical power are used to demonstrate high-sensitivity mid-infrared dual-comb spectroscopy in the important…
Computational coherent averaging for free-running dual-comb spectroscopy
Lukasz A. Sterczewski, Jonas Westberg, Gerard Wysocki
Dual-comb spectroscopy is a rapidly developing technique that enables moving parts-free, simultaneously broadband and high-resolution measurements with microseconds of acquisition…
