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,…
Linewidth of the Laser Optical Frequency Comb with Arbitrary Temporal Profile
Jacob B Khurgin, Nathan Henry, David Burghoff +1
For many applications Optical Frequency Combs (OFCs) require a high degree of temporal coherence (narrow linewidth). Commonly OFCs are generated in nonlinear media from a monochrom…
Computational multiheterodyne spectroscopy
David Burghoff, Yang Yang, Qing Hu
Dual comb spectroscopy allows for high-resolution spectra to be measured over broad bandwidths, but an essential requirement for coherent integration is the availability of a phase…
Terahertz multi-heterodyne spectroscopy using laser frequency combs
Yang Yang, David Burghoff, Darren J. Hayton +3
Frequency combs based on terahertz quantum cascade lasers feature broadband coverage and high output powers in a compact package, making them an attractive option for broadband spe…
