Bistable state photonic crystal

Abstract

The invention discloses a bistable state photonic crystal which is provided with a plurality of holes. A dewatering layer is arranged on the surface of each hole, and when the photonic crystal is immersed in scheduled liquid, the photonic crystal is provided with a first steady state and a second steady state, the first steady state enables the scheduled liquid to be filled in the plurality of holes of the photonic crystal, and the second steady state enables the scheduled liquid to be discharged out of the plurality of holes of the photonic crystal. The bistable state photonic crystal can maintain at any steady state on the premise of needing no external energy due to energy barrier between the first steady state and the second steady state.

Description

technical field [0001] The present invention relates to a bistable photonic crystal, in particular to a photonic crystal capable of maintaining one of two stable states without external energy consumption. Background technique [0002] Photonic crystals are nanostructures with a periodic refractive index, which can change the transmission of light. It is the latest technology that the industry is looking forward to being widely used in future optical communications, displays and optical calculators. At present, the development of photonic crystal technology mainly lies in its manufacturing and driving modulation methods. The traditional photonic crystal color-changing technology mainly uses electrochemical methods, and the refractive index of the material is changed by the expansion of chemical solvents, thus producing color changes. However, the control technology of conventional photonic crystals is limited by the liquid diffusion speed (~10-3m / s) and material limitations,...
