Optimal bistable switching in non-linear photonic crystals
TLDR
An optical bi-stable switch includes a photonic crystal cavity structure, which is used to characterize a bi-stable switch so that optimal control is provided over input and output of the switch as mentioned in this paper.Abstract:
An optical bi-stable switch includes a photonic crystal cavity structure using its photonic crystal properties to characterize a bi-stable switch so that optimal control is provided over input and output of the switch. A plurality of waveguide structures are included, at least one of the waveguide structures providing the input to the switch and at least one providing the output to the switch.read more

Fano resonances in nanoscale structures
TL;DR: In this paper, the authors introduce the concept of Fano resonances, which can be reduced to the interaction of a discrete (localized) state with a continuum of propagation modes, and explain their geometrical and/or dynamical origin.

Enhancement of nonlinear effects using photonic crystals.
TL;DR: If all-optical devices using photonic crystal designs promise to be smaller than the wavelength of light, and to operate with bandwidths that are very difficult to achieve electronically, operation at single-photon power levels could be feasible.
