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 ...

Triangular-profile single-mode fiber

Optics Letters, 1982
A low-loss triangular-profile single-mode fiber is reported. The fiber loss at 1.3-1.55microm wavelengths is below 0.4 dB/km, and its zero-chromatic-dispersion wavelength is 1.402 microm.

All-single-mode fiber resonator

Optics Letters, 1982
An all-fiber-ring resonator has been constructed using a single strand of single-mode optical fiber and a directional coupler. Derivation of the resonator finesse in terms of fiber and directional coupler parameters is given. A finesse of 80 has been achieved experimentally. Applications of such a fiber-ring resonator are discussed.

Bitapered fiber coupling characteristics between single-mode single-core fiber and single-mode multicore fiber

Applied Optics, 2008
By splicing and tapering at the fusion point of one-core single-mode fiber and three- or four-core single-mode fiber, an effective bitapered fiber coupling technique is implemented. Based on the beam propagation method, the bitapered coupling characteristics between the one-core fiber and the multicore single-mode fiber are simulated and analyzed.

Single-mode fiber coupler

Applied Optics, 1981
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.
