Optical fiber sensors (OFS) are developed to replace conventional electro-mechanical sensing systems, which are well established, have proven their reliability and can be manufactured at low cost. Advantages of OFS are resistance to electromagnetic interference, intrinsic safety, mechanical simplicity and small size, the possibly of high sensitivity and(More)

In this letter, we describe a technique for the measurement of the birefringence spatial distribution in a single-mode optical fiber with a resolution of 1 m. This technique is based on a polarization optical time-domain reflectometer using a rotary linear polarizer. We report results performed on different types of fibers: standard step-index and(More)
We investigate a possible extension of the optically connected parallel machine crossbar system to telecommunication routing-switching systems. The critical issue concerns the realization of a free-space interconnection system between two single-mode fiber arrays in the case of a fully interconnected architecture, such as a crossbar system. In particular,(More)
The purpose of this paper is to investigate the performance of microoptics for telecommunication systems using free-space interconnects. This concerns mainly distribution or switching and routing tasks. In order to evaluate the interconnection capability of free-space microoptics, we impose severe conditions on the interconnects. These conditions correspond(More)
