We describe the performance of submicron microdisk and photonic crystal lasers fabricated within InGaP/InGaAlP quantum well material. The smallest lasers, with diameters of approximately 600 nm, feature ultra-small mode volumes and exhibit single mode operation at low threshold powers. Their small cavity volumes of approximately 0.03 μm3 for microdisk lasers and 0.01 μm3 for photonic crystal lasers enable them to be used as spectroscopic sources. Here we demonstrate the fabrication and characterization of visible, monolithically fabricated, submicron mode volume lasers.
