LUNA FPS-001 Phase Shifter
The LUNA FPS-001 is an all fibre device that shifts or modulates phase by up to 15π at frequencies from DC to 20 kHz.
- Low IL, PDL, and residual amplitude modulation
- Frequencies up to 20 kHz
- NoTail model available (minimal OPL)
- Compact
The LUNA FPS-001 is a small, piezo-driven phase shifter that works by stretching a length of fibre. It can provide several π phase shift at frequencies up to 20 kHz. Because the optical path is all in fibre, the device has minimal insertion and return loss. The FPS-001 uses a straight fiber rather than fibre wound on a frame, so the optical path length in fiber is exactly the length of the device from connector tip to connector tip, and can be minimized by controlling the length of the pigtails or by using a NoTail version.
The FPS-001 is useful for small-range phase shifts at frequencies up to 20 kHz. It can be used for fine adjustment or to add a dither in interferometric applications.
