LiNbO3 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.

The analog intensity modulators offered by HC Optical combine high linearity with low drive voltage and small package size, with bandwidths ranging from 20 GHz (AM20) to a wider 40 GHz (AM40). Due to the increasing bandwidth requirements in analog fiber transmission applications, LiNbO3(lithium niobate) intensity modulators for high-bandwidth analog applications from HC Optical can meet higher-end requirements and provide more suitable solutions. Our experience also allows us to provide customized services to our customers.
