Wave Transmission in Dispersive Si-Based One Dimensional Photonic Crystal
Photonic Crystals Omni-Directional Reflection Optical Filter
2013/1/30
Transmission of electromagnetic waves through a Si-based one dimensional photonic crystal has been investigated. The proposed structure works as an omni-directional reflector for a certain range of wa...
Tunable Reflection Bands and Defect Modes in One-Dimensional Tilted Photonic Crystal Structure
Photonic Crystal Structure Photonic Band Gap (PBG) Omnidirectional Reflector Tilted PC Structure De-fect Modes
2013/1/30
We show theoretically that range of reflection bands and defect modes inside the band gap can be tuned by using a one-dimensional tilted photonic crystal (TPC) structure. A TPC structure is similar to...

Mechanically switchable photonic crystal filter either all-pass transmission flat-top reflection characteristics
2015/8/11
We theoretically introduce a new type of optical all-pass filter based on guided resonance in coupled photonic crystal slabs. The filter exhibits near-complete transmission for both on- and off-resona...

2015/8/11
We demonstrate all-optical switching action in a nonlinear photonic crystal cross-waveguide geometry with instantaneous Kerr nonlinearity, in which the transmission of a signal can be reversibly switc...
