High Power Fiber Coupled 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. Common applications include ion trapping, atom cooling and laser locking.

Broadband Free Space Phase Modulator
Have an application that requires a free space setup, higher optical power, lower loss, or a more compact footprint? Contact AdvR for information on our free space modulators. These units are based on the same KTP waveguides as our fiber coupled units, allowing for the same broadband operation and low Vpi with the capability of higher power and lower loss.
