Temperature Effect on THz Quantum Cascade Lasers
A simple semi-phenomenological model, which accurately predicts the dependence of thresholdcurrent for temperature of Resonant-phonon three well quantum cascade laser based on verticaltransitions is offered. We found that, the longitude optical phonon scattering of thermally excitedelectrons is the most important limiting factor for thermal performance of high frequency THz QCLs.In low frequenc...
متن کاملDesign Optimization for 4.1-THZ Quantum Cascade Lasers
We present an optimized design for GaAs/AlGaAs quantum cascade lasers operating at 4.1THz. This was based on a three-well active module with diagonal radiative transition. This was performed by modifying the existing model structure, to reduce the parasitic anticrossings (leakage currents) as well as the optical gain linewidth. While the gain FWHM was reduced by more than 50% the gain pea...

متن کاملTHz quantum cascade lasers with wafer bonded active regions.
We demonstrate terahertz quantum-cascade lasers with a 30 μm thick double-metal waveguide, which are fabricated by stacking two 15 μm thick active regions using a wafer bonding process. By increasing the active region thickness more optical power is generated inside the cavity, the waveguide losses are decreased and the far-field is improved due to a larger facet aperture. In this way the outpu...
متن کاملImproved Active Region Designs for Mode Locking in Quantum Cascade Lasers
Quantum cascade lasers (QCLs) have progressed rapidly due to their intrinsic design potential [1]. These unipolar semiconductor lasers are based on intersubband transitions in multiple quantum-well structures. The design of alternating wells and barriers make QCLs a unique candidate to serve as a semiconductor source of ultra-short pulses in the mid-infrared region [2]. Ultrashort pulses which ...
