Single-Mode–Multimode–Single-Mode Optical Fiber Sensing Structure With Quasi-Two-Mode Fibers

IEEE Transactions on Instrumentation and Measurement, 2018
This 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 ...

Analysis of a tunable single mode optical fiber coupler

IEEE Journal of Quantum Electronics, 1982
We report the operation and the theoretical modeling of an efficient, tunable, and low-loss single mode fiber coupler. The coupler design follows a scheme previously reported, in which two optical fibers mounted in curved grooves in separate quartz substrates are polished until sufficient cladding material has been removed to permit optical coupling ...

Single Mode Fiber Optic Components

IEEE Journal of Quantum Electronics, 1981
In 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, 1980
A 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.
