Abstract

Quantum cascade lasers QCLs1−3 are powerful light emitters in the mid infrared. For chemical sensing, single mode emission is advantageous.4 We fabricated first order distributed feedback lasers to achieve single mode emission. The emission wavelength is continuously tunable according to the temperature dependence of the effective refractive index, which shifts the Bragg wavelength.
