Single-mode operation of a large optically pumped triangular laser with lateral air trenches

Liu, Danyu; Hattori, Haroldo T; Fu, Lan; Tan, Hark Hoe; Jagadish, Chennupati


A triangular resonator has fewer modes than other polygonal lasers such as microdisk and square lasers with similar areas. However, a large resonator with a side of 8 𝜇m can still resonate at many distinct wavelengths. We show experimentally that the introduction of air trenches to the sides of the triangular resonator can lead to single-mode operation of the laser device. The air trenches will considerably increase the radiation losses of most of the resonant modes, except for a mode with...[Show more]
