Fiber Phase Shifter
General Photonics’ all fiber phase shifter/modulator provides phase shifts up to 15π at frequencies from DC to 20 kHz. The all fiber construction practically eliminates insertion loss and back reflection. This compact device is ideal for fiber laser systems, fiber resonators, and fiber interferometers for precision phase tuning or phase modulation.
