Abstract
Single-mode lasing at room temperature in quantum-cascade lasers (QCLs) with arched cavity design has been demonstrated. The output optical power in single-mode lasing regime at ~7.7-μm lasing wavelength was above 6 mW with a side-mode suppression ratio of up to 25 dB. The QCL heterostructure for the arched cavities was grown by molecular-beam epitaxy (MBE) based on a heterojunction of In0.53Ga0.47As/Al0.48In0.52As solid alloys, lattice-matched with InP substrate, and InP layers performing the function of waveguide claddings.
