主　　题：temperature. optical corners 

摘      要：Square microdisks with round corners are fabricated using a standard GaN-based blue LED on Si *** gallery-like inodes in the square microdisks are investigated by finite-difference time-domain *** simulation results reveal that the round corners in square microdisks can substantially suppress the number of light propagation paths and further reduce the number of optical modes.A con focal microphotoluminescence is performed to analyze the optical properties of the square microdisks at room *** single-mode dominant resonant emission is obtained in the square microdisk with corner radius of 1.5μm.
