We present a polarization-independent fiber Bragg grating (FBG) interrogator based on a rapidly-tunable Sagnac interferometer using a dual-polarization lithium-niobate phase modulator. A bandwidth of 100 kHz along a range beyond a full free-spectral-range is demonstrated.

Abstract
We present a polarization-independent fiber Bragg grating (FBG) interrogator based on a rapidly-tunable Sagnac interferometer using a dual-polarization lithium-niobate phase modulator. A bandwidth of 100 kHz along a range beyond a full free-spectral-range is demonstrated.File in questo prodotto:
