Modulate the Amplitude and Phase of Laser Light Using Jenoptik Integrated Optical Light Modulators

The integrated optical modulators allow you to influence the amplitude or phase of laser light quickly and with high dynamics.

Light modulators
The fiber-coupled integrated optical light modulators from Jenoptik are ideal for the amplitude or phase modulation of laser light. You can cover wavelengths of between 500 and 1600 nanometers.

The modulators are based on electro-optical crystals and make use of their rapid electro-optical effect. You can use them to influence the phase or amplitude of light up to high modulation frequencies in the gigahertz range. In addition, the compact devices have a high optical power  stability, low modulation voltages and high extinction ratios.

The light is easily coupled into the integrated optical light modulators using optical fibers and connectors. The modulators can also be equipped with specially adapted control units on request, such as a pulse picker control unit. In addition to standard light modulators, Jenoptik also develops and manufactures customer-specific components to meet your specific requirements.
