LUNA FPS-003 Fibre Phase Modulator/Shifter
The LUNA FPS-003 all fibre 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.
- Wide frequency range (0-60 kHz)
- Small half-wave voltage
- Low IL, PDL, and residual amplitude modulation
- Compact
The LUNA FPS-003 is a small, piezo-driven phase shifter that works by stretching a length of fibre. Like other FPS phase shifters, it employs all fibre 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.
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.
