Electro-Optic ModulatorsThorlabs’ selection of electro-optic (EO) modulators includes free-space and fiber-coupled LiNbO3 modulators. Free-space amplitude, phase, or resonant modulators can operate at speeds up to 100 MHz. Fiber-coupled intensity, phase, or IQ modulators for speeds up to 40 GHz can be driven by our EO modulator drivers. A modulator bias controller is also available for use with fiber-coupled intensity modulators.
For those interested in all-in-one solutions for high-speed fiber optic test and measurement, we offer reference transmitters for both digital and linear applications, optical transmitters with phase modulators, and a calibrated electrical-to-optical converter. All of our transmitters are based on proven lithium niobate modulator technology driven by high-fidelity RF amplifiers. We also offer an EO modulator based on liquid crystal technology and tunable fiber optic laser sources.
