Optical fiber ring resonator characterization by optical time-domain reflectometry.

A novel method for characterization of optical fiber resonators by an optical time-domain reflectometry (OTDR) technique is reported. This easy-to-use technique yields accurate results for cavity lengths ranging from a few meters to several kilometers. A simple relationship is established between the round-trip cavity loss and the position where the OTDR signal is maximum. The value obtained fo...

Optimal detection bandwidth for phase-sensitive optical time-domain reflectometry

The spectrum of the temporal traces obtained from a phase-sensitive optical time-domain reflectometer is theoretically and experimentally analysed, demonstrating its dependence on the incident optical pulse shape. Numerical simulations and theoretical results are validated experimentally, showing a good matching for rectangular optical pulses. The influence of the photodetector bandwidth on the...

Synthetic Spectrum Approach for Brillouin Optical Time-Domain Reflectometry

We propose a novel method to improve the spatial resolution of Brillouin optical time-domain reflectometry (BOTDR), referred to as synthetic BOTDR (S-BOTDR), and experimentally verify the resolution improvements. Due to the uncertainty relation between position and frequency, the spatial resolution of a conventional BOTDR system has been limited to about one meter. In S-BOTDR, a synthetic spect...

High-speed optical coherence domain reflectometry.

Optical coherence domain reflectometry (OCDR) has emerged as an attractive method for obtaining high-spatial-resolution (<10 Am) reflectance measurements of fiber-optic, integrated-optic, and biological structures.` 8 Most previous OCDR systems have achieved high sensitivity and dynamic range by using narrow-band heterodyne detection by piezoelectric path-length modulation and lock-in amplifier...
