Abstract :
Nonpolar GaN two-dimensional photonic crystal (PC) H2 nanocavities have been realized and investigated. One dominated resonant mode was demonstrated at 388 nm with quality factor of approximately 4300 at 77K. Moreover, the degree of polarization of the emission from the non-polar GaN PC nanocavity was measured to be 64% along the m crystalline direction.
