High Efficiency, Low Power-Consumption DFB Quantum Cascade Lasers Without Lateral Regrowth
Abstract Very low power-consumption distributed feedback (DFB) quantum cascade lasers (QCLs) at the wavelength around 4.9 μm were fabricated by conventional process without lateral regrowth of InP:Fe or using sidewall grating. Benefitted from the optimized materials and low waveguide loss, very low...
