This review examines axisymmetric-cavity quantum-dot microlasers whose emission spectrum is determined by whispering-gallery modes. We describe the possible designs, fabrication processes and basic characteristics of the microlasers and demonstrate the possibility of lasing at temperatures above . The feasibility of creating multichannel optical sources based on a combination of a broadband quantum-dot laser and silicon microring modulators is discussed.
