The laser generation characteristics of microdisk lasers with optically coupled waveguide operating in continuous wave mode at elevated temperatures are investigated. Laser generation and waveguide effect at temperatures up to 92.5
$^\circ$ C were demonstrated. The measured characteristic temperature of microlasers was 65 K in the range of 25–92.5
$^\circ$ C.
