Integrated Optical Phase Modulator: Modulate Light with High Frequencies

The Jenoptik integrated optical phase modulator is a fiber-coupled electro-optical light modulator. You can use it in the VIS and IR spectral range.

Phase modulators from Jenoptik
With Jenoptik integrated optical phase modulators, you can influence the phase of light in particularly high modulation frequencies up to the gigahertz range. To do this, the modulator uses the rapid electro-optical effect of special crystals. You can also use the fiber-coupled light modulator in the VIS and IR spectral range.

In the standard version of the integrated optical phase modulators, the light is coupled in and out via polarization-maintaining single-mode fibers. You can also configure the light modulator with other fiber systems or connectors.
