Abstract

See full text

An adjustable optical switch based on a PLZST antiferroelectric photonic crystal, and an adjusting and control method thereof, which belongs to the technical field of micro and nano optoelectronic devices. The adjustable optical switch based on a PLZST antiferroelectric photonic crystal includes an air column type photonic crystal with a diameter of air columns of 420 nm, and a spacing of air columns of 200 nm. According to the present disclosure, a photonic crystal switch is designed by utilizing the coupling property between photonic crystals, and the central wavelength of optical waves is adjusted through the action of the electric field, so that an electro-optical switch with a central wavelength adjustable in a wide range is provided, and has a response speed of less than 1 nanosecond, and the central wavelength can be adjusted in a range of 1100 nm to 1750 nm.
