Abstract

Summary form only given. The 2D photonic crystal (PC) is fabricated in the top cladding layer of an asymmetric active region with a full-width at half-maximum of approximately 60 mn, at room temperature. The photoluminescence (PL) emission at 935 nm, normal to the surface, is enhanced by a factor of 100 and the spectrally integrated PL is enhanced by a factor of 8, both when compared to a reference structure without a PC. When optically pumped above threshold, lasing occurs at a wavelength of 1005 nm. The presented analysis provides a basis for the design of high efficiency LEDs and lasers based on 2D PCs.
