Beam Combining of a Tunable Tilted Quantum Cascade Laser Array

open access: yesAdvanced Photonics Research, EarlyView.
The four‐channel tilted waveguide with varying angles in the quantum cascade laser array, achieving a free tuning range of 100 nm and common‐aperture output simultaneously, is reported. The fabrication eliminates the necessity of electron‐beam lithography and is very promising for mass production in gas sensing industry.
