Abstract

The intensity‐modulation‐based displacement sensor with two receiving fibers is theoretically and experimentally studied. Themathematical model of the proposed sensor is developed and the simulated responses are obtained to be in a good agreement with the experimental results. Compared with the conventional sensor with only one receiving fiber, the proposed sensor has a better linearity range because it has a larger area to receive the reflected light from the target. However, the sensitivity of both sensors is almost similar. Theproposed sensor has the maximum linearity ranges of 2.5 μm and 0.9 μm at the back and front slopes, respectively. The linearity ranges are improved by about 44% compared with the conventional sensor. © 2009 Wiley Periodicals, Inc.

A new method for fabricating double fiber Bragg gratings at the same location on a fiber is described. Two series of refractive index change in a fiber, not similar to the normal fiber grating, have been realized by a Fresnel prism interferometer. As a result, the transmission spectrum of the fiber

## Abstract In this paper, we present a simple analytical method based on coordinate transformation for the calculation of the dispersion characteristics of an optical fiber which is slightly flattened on one side. We choose the new and appropriate orthogonal coordinates (ξ, η, __z__) for the propo
