Electro-Optic Intensity Modulator

Intensity modulator is an optical device used to modulate the intensity (optical power) of an optical signal. It is widely used in optical communications, lidar, optical fiber sensing and other fields.Its core principle is to control changes in light intensity through electrical signals or optical signals.

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.
