Paper Abstract

Using a range of grating pitches, we obtained distributed feedback (DFB) quantum cascade lasers (QCL) operating CW at room temperature over the 9-11μm range. Single mode CW operation is demonstrated up to 10.8 μm, and up to 40 °C. To the best of our knowledge, it is the longest wavelength reported for a DFB QCL operating CW above room temperature. The wavelength coverage per wafer is larger than 110 cm-1. DFB QCLs from two wafers which have different gain peaks have lasing wavelengths near optical absorption peaks of glucose.
