Transmission measurement of the photonic band gap of GaN photonic crystal slabs
J. Caro, E. M. Roeling, B. Rong, Hoang M. Nguyen, E. W. J. M. van der Drift et al.
A high-contrast-ratio (30 dB) photonic band gap in the near-infrared transmission of hole-type GaN two-dimensional photonic crystals (PhCs) is reported. These crystals are deeply etched in a 650 nm thick GaN layer grown on sapphire. A comparison of the measured spectrum with finite difference time d ... [Appl. Phys. Lett. 93, 051117 (2008)] published Fri Aug 8, 2008.
