Paper Abstract

InP-based 1.6 micrometer microcavity light emitting diodes (MCLEDs) have been designed, fabricated and characterized. Oxide-confined MCLEDs with lateral aperture size down to 1 micrometer have been realized with enhanced output slope efficiency and excellent spectral and spatial properties. Both mirror-free cylindrical MCLEDs with oxide-aperture and 3D MCLEDs have been fabricated and a maximum output power of 0.03 mW at 30 mA for a 30 micrometer device has been realized. The effect of the aperture size on the slope efficiency and spatial properties have been systematically investigated, which shows an enhanced slope efficiency and narrower emission angle for small aperture size devices. The temperature dependent cavity properties have also been carefully examined for both the active region emission peak and cavity resonance peak.
