Abstract

A small-aperture oxide-confined holey light-emitting diode (LED) on p-type GaAs substrate in the 830 nm range is reported. The device is consisted of bottom distributed Bragg reflector (DBR), quantum wells (QWs), and top DBR, with a small-aperture holey structure at the center for light extraction. The internally reflected spontaneous emission can be extracted and collimated out of the etched hole. High-resolution imaging studies indicate that the device emits with a narrower beam mainly through the central etched hole region made it suitable for fiber-optic applications.
