Enhanced light extraction by photonic quasi-crystals in GaN blue LEDs
Shields, Philip A., Charlton, Martin, Lee, Tom, Zoorob, Majd and Allsopp, Duncan (2009) Enhanced light extraction by photonic quasi-crystals in GaN blue LEDs. IEEE Journal of Selected Topics in Quantum Electronics, 15, (4), 1269-1274. (doi:10.1109/JSTQE.2009.2016674).
The far-field profile of photonic quasi-crystal patterned and unpatterned LEDs, fabricated from commercial epitaxial substrates by electron beam lithography, has been measured prior to lapping and dicing. Emission enhancements reach a maximum of 62%, and are strongly dependent on the filling factor. Qualitative agreement is achieved between 2-D finite-difference time-domain calculations and the experimental data.
