Bistable switching in chalcogenide 1D photonic crystal nanocavities

Abstract

Photonic crystal (PhC) nanocavities have attracted much attention recently for their high-Q, low-volume resonances, with applications in optical switching, cavity quantum electrodynamics, sensing, and many others. While the highest Q-factors have been reported in 2D planar photonic crystal cavities, interest has been growing in 1D waveguide nanocavities [1]. These offer many benefits over 2D cavities, including ease of design and fabrication, small size, and the ability to confine light in material systems with index contrasts too low to support 2D photonic bandgaps [2,3].
