FPS-003

Fiber Phase Shifter

The FPS-003 all fiber phase shifter/modulator combines a wide modulation bandwidth (up to 60 kHz) with low half-wave voltages to create a long-range device that can be driven by standard function generators.

Product Description

The FPS-003 is a small, piezo-driven phase shifter that works by stretching a length of fiber. Like other FPS phase shifters, it employs all fiber construction and has low insertion loss and back reflection. It has a low half- wave voltage and a higher frequency range and resonance frequency than the FPS-002.

Solutions and Applications

The FPS-003 is useful for phase shifts of up to several tens of π at frequencies up to 60 kHz. Especially when used at resonance, the Vπ is very small, so it can be driven by a function generator. It can be used for fine adjustment or to add a dither in interferometric applications.
