A vertical GaN-light emitting diode (LED) has been fabricated on a sapphire substrate with periodic via holes formed by a laser drilling technique. n-contact metal which was deposited on the backside of sapphire substrate was directly connected with

Theoretical and experimental investigations have shown that the omnidirectional photonic band gap (omni-PBG) of one-dimensional photonic crystals (1D PCs) can be enlarged by including multiple-periodic structures. These structures, consisting of Si

The Si/SiO2 one-dimensional photonic crystals of heterostructural multilayers with two periods, ΛA and ΛB, have great potential for multiple-wavelength-transmission filters. These structures were prepared by inserting N pairs of ΛB (as the defect
