Intensity Modulator
Product Description
HC-BN series electro-optic intensity modulators utilize the electro-optic effect of lithium niobate crystals and adopt push-pull Mach-Zehnder interference structure to realize the intensity modulation of optical signals. They have the characteristics of low insertion loss, high modulation bandwidth, high extinction ratio, low half-wave voltage, and high damage optical power.
