متن کاملLow-divergence single-mode terahertz quantum cascade laser
The operation of quantum cascade lasers has to date been demonstrated over a broad frequency range in the terahertz spectrum (from 4.4 THz to 1.2 THz)1–3. Most potential applications of terahertz quantum cascade lasers require a source that has an excellent spatial and spectral control of the radiated emission4–7. Here, we present a distributed feedback design of a double-metal waveguide quantu...
متن کاملHyperuniform 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 کاملLow-threshold optically pumped lÄ4.4mm vertical-cavity surface-emitting laser with a PbSe quantum-well active region
We report pulsed emission from an optically pumped lead-salt vertical-cavity surface-emitting laser with a PbSe/PbSrSe quantum-well active region. The lasing wavelength of l54.44 mm is nearly constant over the temperature range 200–280 K, and the threshold is only 10.5 kW/cm at 260 K, where the gain peak and cavity mode are in resonance. Over 330 mW of peak power is emitted at 260 K, into a cir...
