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 µm 3 for microdisk lasers and 0.01 µm 3 for photonic crystal lasers enable them to be used as spectroscopic sources. Here we demonstrate the fabrication and
