- Abstract
Single-Mode Electrically Pumped Terahertz Laser in an Ultracompact Cavity via Merging Bound States in the Continuum (Laser Photonics Rev. 17(11)/2023) This surface-emitted laser is highly energy-efficient and monolithically integrated which displays a nontrivial cylindrical vector beam profile. B Single-Mode Electrically Pumped Terahertz Laser in an Ultracompact Cavity via Merging Bound States in the Continuum b In article number 2300350, with merging symmetry-protected and accidental bound states in the continuum (BIC) modes, Song Han, Qi Jie Wang, and colleagues demonstrate an electrical pumping BIC quantum cascade laser (QCL) in the Terahertz regime with single-mode lasing operation (with a side-mode-suppression-ratio of ~20 dB) in an ultra-compact cavity with a pump area of around 4 SP 2 sp .
