Description
The KY-AM series electro-optic intensity modulator utilizes the electro-optical effect of lithium niobate,and push-pull Mach-Zehnder interference structure to achieve intensity modulation of optical signals. It features low insertion loss, high modulation bandwidth, high extinction ratio, low half-wave voltage and high damage optical power. This product is mainly used for electro-optical signal conversion in high-speed optical fiber communication systems, the generation of light sidebands, high extinction ratio light pulse generation in quantum communication, microwave fiber link and other fields.
