(author), Llombart, Nuria (author), Mehdi, I. (author), Chattopadhyay, G. (author)Terahertz heterodyne spectrometer instruments have been traditionally limited to a single pixel or a handful of pixels due to integration and assembly constraints and a limited availability of local oscillator (LO) power. As a solution we propose a novel silicon-micromachined planar and modular packaging strategy, that will allow for a dense...conference paper 2023

(author)We present an 8-beam local oscillator (LO) for the astronomically significant [OI] line at 4.7 THz. The beams are generated using a quantum cascade laser (QCL) in combination with a Fourier phase grating. The grating is fully characterized using a third order distributed feedback (DFB) QCL with a single mode emission at 4.7 THz as the input....journal article 2017

Mirzaei, B. (author), van Marrewijk, N.T. (author), Hayton, D (author), Gao, J.R. (author), Kao, T. Y. (author), Hu, Q. (author), Reno, John L. (author)We have performed frequency locking of a dual, forward reverse emitting 3rd order distributed feedback quantum cascade laser (QCL) at 3.5 THz. By using both directions of THz emission in combination with two gas cells and two power detectors, we can for the first time perform frequency stabilization, while monitor the frequency locking...conference paper 2017
