Substrate-emitting quantum cascade lasers with a distributed Bragg reflector and a spectrally detuned second-order outcoupler
Demonstration of substrate-emitting quantum cascade lasers (QCLs) with a distributed Bragg reflector (DBR) used for wavelength selection and a second-order outcoupler spectrally detuned from the reflector is reported. A 40-stage QCL structure with the gain spectrum centered at 4.1 μm was processed i...
