Electro-Optic Modulators


 
High Power Fiber Coupled Optical Phase Modulators

AdvR has developed a phase modulator in a KTP waveguide to operate in wavelengths ranging from near-infrared to near-ultraviolet. The use of KTP waveguides enables modulators with high power handling and low Vπ . Performance has been optimized in single mode 780nm phase modulators, but contact AdvR to discuss custom configurations to meet your application's needs.

AdvR is able to produce phase modulators at customer specified wavelengths from the near-ultraviolet into the near-infrared. These custom phase modulators are produced with similar specifications as the 780nm phase modulator with some variation in maximum power, Vpi, and insertion loss depending on the wavelength. Currently these modulators are spec'd for multimode operation with temperature control to ensure performance stability.
