Our fiber-optic phase modulators provide phase modulation in a broad operation bandwidth with a low driving voltage. They have a low insertion loss for maximum transmission power. They use Annealed Proton Exchange (APE) optical waveguides and polarization-maintaining input and output fibers, making it easy to integrate with other optical components.

Both our phase and our amplitude modulators are based upon the Pockel's effect: the electro-optic effect where the refractive index along one or more axes is proportional to an externally applied electric field. Therefore, by applying a voltage across the electrodes of an electro-optic crystal, you can change the phase of light as it passes through the crystal. By placing the crystal between crossed polarizers, this phase modulation can be converted into amplitude modulation.
