Photonic Crystal Optical Switch Using Line Defects
The self-collimation(SC) effect of photonic crystals(PCs) achieves collimated radiation with almost no diffraction effect when the incident light propagates along a particular direction of the crystal. Line defects in 2D PCs cause bending and splitting of the SC beam. In this example, the effect of "optical switching" can be achieved by altering the line defects (radius of the dielectric rod) in the photonic crystal.
Photonic Crystal Bragg Fiber
Bragg fiber is a type of air-core fiber that allows light to propagate in the air core, which avoids problems caused by intrinsic material limitation. In this example, we use SimWorks Finite Difference Solutions to calculate the modes of the PC Bragg fiber described by Vienne et al and further compare the results with those from Uranus et al.
