Abstract | The polarization behavior of light emission from InGaN light-emitting diodes (LEDs) with nanosphere opal coatings has been studied. The close-packed nanosphere opal films are self-assembled with 220-nm polystyrene nanospheres onto the LEDs. The optical transmission properties of transverse electric and transverse magnetic polarized light have been measured as a function of detection angle; an integrated $p/s$ ratio of 2.2 has been obtained at a detection angle of 70 The polarization of light propagating through the opal film is strongly related to the photonic bandgap of the 3-D photonic crystal and is also dependent upon the angle of incidence. Theoretical calculations by the transfer matrix method are found to be consistent with the measured results. © 1989-2012 IEEE. |
