Wavelength dependent phase locking in quantum cascade laser Y-junctions
L. K. Hoffmann, C. A. Hurni, S. Schartner, E. Mujagic, A. M. Andrews et al.
Midinfrared quantum cascade lasers with monolithically integrated Y-junctions are investigated. Two different emission wavelengths of 10.5 and 4.2 [mu]m were realized in two different material systems, lattice-matched GaAs/AlGaAs on GaAs and strain-compensated InGaAs/InAlAs/AlAs on InP. With identi ... [Appl. Phys. Lett. 92, 061110 (2008)] published Thu Feb 14, 2008.
