Abstract

GaAs/Al_o.3Ga_o.7As quantum-well LEDs with an asymmetric photonic-crystal structure in the 850 nm range is reported. The device consists of bottom distributed Bragg reflector (DBR), quantum wells (QWs), and top DBR, with a photonic-crystal structure formed within the p-type ohmic contact ring for light extraction. The collimated light output was obtained using an asymmetric photonic-crystal structure for light extraction. The spontaneous emission can be transmitted out of photonic-crystal air-holes.
