Overview
The FPS-003 is a small, piezo-driven fiber phase shifter/modulator that works by stretching a length of fiber. It combines a modulation bandwidth of up to 60 kHz with low half-wave voltages, so it can be driven by standard function generators.
Like the other FPS phase shifters, the FPS-003 uses all-fiber construction with low insertion loss and back reflection. Compared with the FPS-002, it has a higher frequency range and a higher resonance frequency.
The device supports phase shifts of up to several tens of π at frequencies up to 60 kHz. When operated at resonance, the half-wave voltage (Vπ) is very small. Typical uses include fine phase adjustment or adding a dither in interferometric setups, as well as precision phase tuning or phase modulation in fiber sensor systems, fiber laser systems, fiber resonators and fiber interferometers.
The FPS-003 has been discontinued by the manufacturer; the FPS-001 and FPS-002 fiber phase shifters are listed as replacement products.
