Fedorova, Ksenia A.; Gorodetsky, Andrei A.; Livshits, Daniil A.; Maleev, Nikolai A.; Blokhin, Sergei A.; Soboleva, Ksenia K.; Ustinov, Victor M. and Rafailov, Edik U. Broadly tunable dual-wavelength InAs/GaAs quantum-dot laser for THz generation. IN: Proceedings : 2016 International Conference Laser Optics. IEEE.


We demonstrate an ultra-compact, room-Temperature, continuous-wave, broadly-Tunable dual-wavelength InAs/GaAs quantum-dot external-cavity diode laser in the spectral region between 1150 nm and 1301 nm with maximum output power of 280 mW. This laser source generating two modes with tunable difference-frequency (300 GHz-30 THz) has a great potential to replace commonly used bulky lasers for THz generation in photomixer devices.
