A team led by Researcher Meng Bo at the Changchun Institute of Optics, Fine Mechanics and Physics published a paper in Laser & Photonics Reviews presenting a mid-infrared quantum cascade laser with a goblet-shaped waveguide structure, using selective wet etching of the active region and eliminating the semi-insulating InP lateral regrowth process. A 1 mm x 3 um device achieved a continuous-wave threshold power consumption of about 1 W at 293 K, an output power above 27 mW, and a room-temperature pulsed wall-plug efficiency of 3.9%. A 2 um-wide device achieved stable single-mode lasing across the entire current range, with a side-mode suppression ratio of about 20 dB.
Why we recommend it: The goblet-shaped waveguide eliminates the semi-insulating InP regrowth process through selective wet etching. The original paper gives room-temperature continuous-wave threshold power consumption and wall-plug efficiency, which can be compared with buried heterostructure devices for context.

A team led by researcher Meng Bo at the Changchun Institute of Optics and Mechanics published a paper in Light: Science & Applications proposing a multistate-to-continuum (MTC) active-region design based on diagonal transitions, and used MOCVD to grow a mid-infrared quantum cascade laser with a single active region and an ultrabroad gain spectrum.
Why we recommend it: The diagonal-transition design from multiple states to continuum states lets several transition channels contribute gain simultaneously. The original text gives lasing spectral widths of 1.2 µm at room temperature and 1.93 µm at 80 K, directly relevant to applications such as mid-infrared frequency combs.
