Abstract
Precise and accurate length measurements of optical fibers are increasingly needed across various applications. However, many commercially available devices are either too inaccurate or, conversely, too advanced and costly for basic fiber length determinations. In this Letter, we present a simple and relatively inexpensive method to measure the length of optical fibers with a precision of 1.06 ps (∼212 μm). This method exploits the relationship between the phase difference of a fiber under test (FUT) and a calibrated reference path as a function of frequency, measured by a phase-locked loop during a frequency sweep. We highlight key processing steps to achieve reproducible results and important considerations regarding environmental conditions.
期刊介绍：
The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community.
Optics Letters offers rapid dissemination of new results in all areas of optics with short, original, peer-reviewed communications. Optics Letters covers the latest research in optical science, including optical measurements, optical components and devices, atmospheric optics, biomedical optics, Fourier optics, integrated optics, optical processing, optoelectronics, lasers, nonlinear optics, optical storage and holography, optical coherence, polarization, quantum electronics, ultrafast optical phenomena, photonic crystals, and fiber optics. Criteria used in determining acceptability of contributions include newsworthiness to a substantial part of the optics community and the effect of rapid publication on the research of others. This journal, published twice each month, is where readers look for the latest discoveries in optics.
