Title:
TWO-LAYER PHOTONIC CRYSTAL PHOTOSWITCH THIN-FILM DEVICE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/103738
Kind Code:
A1
Abstract:
A two-layer photonic crystal photoswitch thin-film device having the optical characteristics of both 2D and 3D photonic crystals, and a preparation method therefor. When the two-layer photonic crystal photoswitch thin-film device is rotated periodically, different colors can be observed at a fixed rotation angle, that is, the device has the attribute of changing colors by means of rotation, and can thus realize the opening and closing of an optical path. The new two-layer photonic crystal photoswitch thin-film device has broad application prospects in the fields of photoswitches, optical waveguides, optical prisms, warning signs, anti-counterfeiting, information coding, etc.
