Study presents ultra-low threshold continuous-wave quantum dot mini-BIC lasers
https://phys.org/news/2023-07-ultra-low-threshold-continuous-wave-quantum-dot.html
"CW operated BIC lasers low-thresholds and small V-modes combining O-band InAs/GaAs epitaxial QD gain material mini-BIC cavities... 3D confinement light and carriers provided by mini-BIC cavity and QD, ultra-low threshold >20 μW and small size ~2.5×2.5 μm2... no requirement long-range periodicity... discrete state converge accidental BIC modes k-space... small footprint, ultralow threshold and adaptability,.. high-capacity optical communications, sensing, chip-scale solid-state LIDAR and quantum information"
