Electro-Optic Modulators

Thorlabs’ 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. We also offer liquid crystal EO modulators for speeds up to 2.5 kHz.

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.
