Abstract

The invention belongs to the field of optical devices. The problem that an existing infrared window material is not high in laser energy threshold value, and consequently the material is prone to damage is solved. The invention discloses an intelligent infrared light switch for an infrared window material and a manufacturing method, the working wavelength is infrared light, and the intelligent infrared light switch is characterized by comprising an infrared filter layer, a semiconductor-metal phase change material layer and a transparent substrate layer in the working wavelength in sequence inthe light propagation direction; the infrared filter layer is used for shielding light of a wave band outside the working wavelength and enabling infrared light of the working wavelength to pass through; when the temperature of the semiconductor-metal phase change material layer is lower than the phase change threshold value, the semiconductor-metal phase change material layer is in a semiconductor state, infrared light with the working wavelength passes through, when the temperature of the semiconductor-metal phase change material layer is higher than the phase change threshold value, the semiconductor-metal phase change material layer is in a metal state, and infrared light with the working wavelength cannot pass through. By using the technical scheme, the incident light waveband of the specific infrared light can be intelligently adjusted.

Description

technical field [0001] The invention relates to the technical field of photoelectric devices, in particular to an intelligent infrared light switch used for infrared window materials. Background technique [0002] The infrared photoelectric system is an important part of modern high-precision weapons and the key to achieving precise strikes and effective attacks. It has been widely used in advanced weapons such as supersonic fighters and guided missiles. In the infrared photoelectric system, the infrared window is the only channel to transmit the emission signal and receive the target signal, and its optical properties directly affect the detection results of the photoelectric system. In addition, the infrared window is exposed to the external environment, and also undertakes the mission of protecting the internal optoelectronic components. Therefore, the infrared window is one of the important components of the infrared photoelectric system. [0003] As for the current in...
