Design Optimization for 4.1-THZ Quantum Cascade Lasers

نویسندگان

چکیده مقاله:

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 peak was increased by about 23.3%.‎

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...

Optimization of MBE Growth Parameters for GaAs-based THz Quantum Cascade Lasers

Solid state terahertz (THz) lasers were made possible through the rapid progress in quantum cascade lasers (QCLs) [1]. Despite the advances in mid-infrared (MIR) QCLs [2], THz QCLs remain difficult to fabricate. The tolerances in alloy composition, layer thickness, and doping are lower for THz QCLs than their MIR counterparts. Typical THz structures can require more than a day to grow by MBE an...

Hot-phonon generation in THz quantum cascade lasers

Observation of non-equilibrium optical phonons population associated with electron transport in THz quantum cascade lasers is reported. The phonon occupation number was measured by using a combination of micro-probe photoluminescence and Stokes/Anti-Stokes Raman spectroscopy. Energy balance analysis allows us to estimate the phonon relaxation rate, that superlinearly increases with the electric...

THz 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...

“High-temperature and high-power THz quantum cascade lasers”

The highest temperature performance in terahertz QCLs has been demonstrated by using active regions based on the resonant-phonon depopulation scheme along with metalmetal waveguides to provide low-loss confinement, which have been used to demonstrate maximum temperatures of 164 K in pulsed mode and 117 K in cw mode. It is expected that there are two primary mechanisms which reduce the populatio...
