«Output Power of III-V Injection Microdisk and Microring Lasers» (2025) Kryzhanovskaya N.V. et al. — IEEE Journal of Selected Topics in Quantum Electronics.
The paper analyses whispering-gallery-mode (WGM) microdisk and microring lasers based on III–V compounds. Owing to their minute size and extreme sensitivity to the surrounding refractive index, such devices enable microlaser sensors and fundamental studies of quantum chaos. Yet the low output-coupling loss in high-Q resonators can negate practical advantages. The authors compile published data on attainable optical output power in injection-driven III–V microlasers and identify the main limiting factors, notably self-heating under continuous-wave operation and inefficient light extraction from WGM resonators. They also compare various III–V material systems and fabrication techniques aimed at boosting output power.
«Mode leakage into substrate in microdisk lasers» (2024) Melnichenko I.A. et al. — St. Petersburg Polytechnic University Journal. Physics and Mathematics.
Experiment and modelling were used to study leakage of whispering-gallery modes from a quantum-dot injection microdisk laser into a GaAs substrate. For a 50 µm-diameter device with 1.5 µm-thick Al0.4Ga0.6As claddings, the leaked-mode intensity can reach ~10-3 of that inside the waveguide.
