摘要

A tapered distributed feedback quantum cascade laser emitting at λ ～ 8.1 μm is reported. Utilising a tapered waveguide structure with a surface metal grating, the device exhibited singlemode operation over the temperature range of 100 to 214 K, with sidemodc suppression ratio >20 dB and a nearly diffraction limited far-field beam divergence angle of 5.4 .
