We report about RF injection locking of an homogeneous THz quantum cascade laser operating at 3 THz central frequency. The extremely diagonal nature of the optical transition, combined with low-loss copper-based double-metal waveguides, allow CW oper

We report about high temperature comb operation of THz quantum cascade lasers. The extremely diagonal nature of the optical transition combined with low loss copper-based double-metal waveguides allow CW operation up to 105 K and CW power in excess o

Avalanche photodetectors (APDs) are key components in optical communication systems due to their increased photocurrent gain and short response time as compared to conventional photodetectors. A detector design where the multiplication region is impl

2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
We present THz QCLs based on two quantum wells per period, designed and optimized with a nonequilibrium Green's function model, which lase up to 210 K cryostat temperature using a dry etched Cu-Cu double-metal waveguide.

We present a \MF{terahertz} quantum cascade laser operating on a thermoelectric cooler up to a record-high temperature of 210.5 K. The active region design is based on only two quantum wells and achieves high temperature operation thanks to a systema

THz quantum cascade lasers (QCLs) have been limited to operation below 200 K [1], despite large efforts towards improving active region design and minimizing device losses [2]. The former has typically been done using simplified models with fast calc
