Abstract

This paper discusses the operation of an oxide-confined vertical-cavity surface-emitting laser (VCSEL) featuring a submicroampere threshold current. Several measurements including polarization, linewidth, optical beam profile, and light-current characteristics confirm that the device is operating as a laser at currents less than 1 μA. Spectroscopic and far-field measurements are used to analyze the laser's modal structure and operation.
