Single-mode fiber components

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.

Expanded single mode fiber

OFC 2001. Optical Fiber Communication Conference and Exhibit. Technical Digest Postconference Edition (IEEE Cat. 01CH37171), 2001
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.

Polarization maintaining Single-mode fibers

Conference on Lasers and Electro-Optics, 1981
Polarization-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.

Design and numerical analysis of highly birefringent single mode fiber in THz regime

Optical fiber technology (Print), 2019
A novel kind of porous core microstructure optical fiber is proposed in this paper. In order to create flexibility of the fiber only ring air hole is used for the cladding region.

Refractive index sensor based on ultrafine tapered single-mode nocladding single-mode fiber structure

Optical fiber technology (Print), 2019
A refractive index (RI) sensor based on a tapered no cladding fiber (NCF) is proposed theoretically and experimentally. The RI sensor is fabricated by splicing a NCF in the middle of two single mode fibers (SMF), and then the NCF is tapered to get lower ...

Single-mode fiber measurements

IEEE Transactions on Instrumentation and Measurement, 1986
In 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, 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.

Single-Mode Fiber-Type Polarizer

IEEE Transactions on Microwave Theory and Techniques, 1982
The simple and novel fabrication technique of the fiber-type polarizer has been demonstrated and the polarization characteristics of the polarizer have been investigated. The polarizer structure consists of the eccentric core and the metal coat on the thin buffer layer whose thickness is controlled by chemical etching.
