| Outline of Final Research Achievements |
We have studied on the development of III-nitride light emitting diode(LED) by using subwavelength periodic structure. Especially, we have examined the high polarized light emitting diode in UV wavelength region. By the theoretical analysis of the eigen-mode and the calculation of the electromagnetic distribution within the subwavelength lattice region, we determined the optimum condition of the subwavelength grating for the fabrication of highly polarized UV-LED. We have succeeded the development of UV-LED with high polarization selectivity, p:s=18:1.
