lambda \sim \ \mum Distributed-Feedback Quantum-Cascade Lasers With High-Aspect-Ratio Lateral Grating

We report the development of room-temperature distributed-feedback quantum-cascade lasers operating in a single mode in the 3.34 to 3.35 μm wavelength range. First-order lateral gratings with high aspect ratio (the ratio between the grating etch depth and its period) were formed using inductively co...
