Fiber Phase Shifter

Coherentorinterferometricsensorsystems,suchasdistributedacousticsensors(DAS),oftenrequire a low loss, low-cost phase shifter or modulator to obtain the desired sensing signals. GeneralPhotonics’2nd generation all fiber phase shifter/modulator provides phase shifts up to 75πwithamuch lowerhalf-wavevoltage (~2voltsascomparedwith10-20volts forthe 1stgenerationphaseshifter)atfrequenciesfromDCto20kHz.Theallfiberconstructionpracticallyeliminates insertion lossandbackreflection. Inaddition to fibersensorsystems,this compact device is ideal for fiber laser systems, fiber resonators, and fiber interferometers for precision phase tuning or phase modulation.
