Electro-Optic Intensity Modulator
Product introduction
HC-BN series electro-optic intensity modulators use the electro-optic effect of lithium niobate crystal to realize the intensity modulation of optical signals by using push-pull Mach-Zehnder interference structure. They have the characteristics of low insertion loss, high modulation bandwidth, high extinction ratio, low half-wave voltage and high damage optical power. They are mainly used for electro-optic signal conversion and optical sideband generation in high-speed optical communication systems. High extinction ratio optical pulse generation in quantum communication and microwave optical fiber links.
