We demonstrate of a metal grating purely index coupled distributed feedback quantum cascade Lasers at around 7.5mum. It presents a large tuning without broadband gain and side mode suppression ratio ...
The electromagnetic waves carrying orbital angular momentum can achieve azimuthal resolution for radar imaging without relative motion. However, the difference of main-lobe direction of different ...
