Terahertz semiconductor laser source at -12 C
Ali Khalatpour, Man Chun Tam, Sadhvikas J. Addamane +3
Room temperature operation of Terahertz Quantum Cascade Lasers (THz QCLs) has been a long-pursued goal to realize compact semiconductor THz sources. The progress toward high-temper…
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…
Hot electron bolometer heterodyne receiver with a 4.7-THz quantum cascade laser as a local oscillator
Jenna L. Kloosterman, Darren J. Hayton, Yuan Ren +7
We report on a heterodyne receiver designed to observe the astrophysically important neutral atomic oxygen [OI] line at 4.7448 THz. The local oscillator is a third-order distribute…
Thresholdless Coherent Light Scattering from Subband-polaritons in a Strongly-Coupled Microcavity
Johannes Gambari, Antonio I Fernandez-Dominguez, Stefan A Maier +5
We study a "strongly-coupled" (SC) polariton system formed between the atom-like intersubband transitions in a semiconductor nanostructure and the THz optical modes that are locali…
Coherence of resonant-tunneling transport in terahertz quantum-cascade lasers
Sushil Kumar, Qing Hu
We develop simple density-matrix models to describe the role of coherence in resonant-tunneling (RT) transport of quantum-cascade lasers (QCLs). Specifically, we investigate the ef…
