Single-Mode–Multimode–Single-Mode Optical Fiber Sensing Structure With Quasi-Two-Mode Fibers
IEEE Transactions on Instrumentation and Measurement, 2018This paper reviews some aspects of optical fiber sensors based on a single-mode (SM)-multimode (MM)-SM structure and reports on the realization of temperature sensors in which the MM section is made by a quasi-two mode fiber. Two different realizations are compared that rely on: 1) a bend-insensitive fiber operated in the second optical communication ...

Proceedings of the IEEE, 1987
A variety of optical components have been made directly from single-mode fibers. These components can be combined to construct in-line all-fiber systems such as fiber gyroscopes, fiber Raman lasers, local area networks, or coherent lightwave systems. This paper reviews the present state of passive and active single-mode fiber components.

We present a solution to maintain an expanded mode in the extremity of a single mode fiber by using a piece-of multimode step index fiber. With a 25 /spl mu/m spot size, the average connection loss is 0.36 dB (without Fresnel reflection) for a multimode section length inferior to 5 cm.

This paper describes the fabrication process and coupling principle of a single-mode fiber coupler. Precise etching properties of the fibers used are presented. Fiber etching is shown to result in smooth surfaces. Coupling is seen to vary with the refractive index of the material separating the fiber cores.

Polarization maintaining Single-mode fibers
Conference on Lasers and Electro-Optics, 1981Polarization-maintaining single-mode fibers will find application in acoustooptic sensors and fiber gyroscopes. In this study both stress-induced birefringence and elliptical core polarization-maintaining single-mode fibers were developed and evaluated.

Single-mode fiber measurements
IEEE Transactions on Instrumentation and Measurement, 1986In this invited tutorial review paper on single-mode fiber measurements, I discuss the various methods used to characterize the following important transmission parameters of single-mode fibers: attenuation, cut-off wavelength, mode-field diameter and chromatic dispersion.

Single Mode Fiber Optic Components
IEEE Journal of Quantum Electronics, 1981In the process of studying single-mode fiber optic systems it became rapidly apparent a few years ago that it would be desirable to perform a number of functions with in-line components, which would allow for signal processing without the removal of the optical signal from the fiber.

Single-mode fiber-optic polarizer
Optics Letters, 1980A technique is presented for the fabrication of high-quality single-mode fiber-optic polarizers. Properties of polarizers made using this technique include extinction ratios in excess of 60 dB as well as low loss for the desired polarization.

Single-mode optical fiber cable
Applied Optics, 1979A single-mode optical fiber cable was manufactured; loss increase characteristics due to cabling were evaluated. The existence of wide V-value regions without cabling loss increases is shown by a suitable selection of fiber parameters and optical wavelengths.

Single-mode optical fiber goniometer
Optics Letters, 1992A two-element single-mode optical fiber goniometer that uses graded-index microlens receivers is presented that measures the angular orientation of a remote laser. The goniometer exhibits a sensitivity of 1.0 V/mrad and a calculated shot-noise-limited angular resolution of 1.0 nrad/ radicalHz.
