Hyperuniform disordered terahertz quantum cascade laser
Laser cavities have been realized in various different photonic systems. One of the forefront research fields regards the investigation of the physics of amplifying random optical media. The random laser is a fascinating concept because, further to the fundamental research investigating light transport into complex media, it allows us to obtain non-conventional spectral distribution and angular...

متن کاملSpectral behavior of a terahertz quantum-cascade laser.
In this paper, the spectral behavior of two terahertz (THz) quantum cascade lasers (QCLs) operating both pulsed and cw is characterized using a heterodyne technique. Both lasers emitting around 2.5 THz are combined onto a whisker contact Schottky diode mixer mounted in a corner cube reflector. The resulting difference frequency beatnote is recorded in both the time and frequency domain. From th...
متن کاملEvidence for frequency comb emission from a Fabry-Pérot terahertz quantum-cascade laser.
We report on a broad-band terahertz quantum-cascade laser (QCL) with a long Fabry-Pérot ridge cavity, for which the tuning range of the individual laser modes exceeds the mode spacing. While a spectral range of approximately 60 GHz (2 cm(-1)) is continuously covered by current and temperature tuning, the total emission range spans more than 270 GHz (9 cm(-1)). Within certain operating ranges, w...
متن کاملElectromagnetic Modeling of Terahertz Quantum Cascade Laser Waveguides and Resonators
Finite-element numerical modeling and analysis of electromagnetic waveguides and resonators used in terahertz (THz) quantum cascade lasers (QCLs) is presented. Simulations and analysis of two types were performed: two-dimensional waveguides, and twoand three-dimensional resonators. Both metal-metal and semi-insulating (SI) surface-plasmon geometries were investigated. Waveguide simulations exte...
