In this article, the present state of passive and active single-mode fiber components are reviewed, including polarizers, directional couplers, filters, and Faraday rotators.
Abstract
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. Passive components are polarizers, directional couplers, filters, and Faraday rotators. Active components require external control or optical power and include modulators, polarization controllers, frequency shifters, and amplifiers. Polarization is usually important in fiber components and discussions of polarization-maintaining and ordinary single-mode fibers are included.

IV Advanced Evaluation Techniques in Interferometry

TL;DR: This chapter describes the advanced evaluation techniques in interferometry and identifies the types of error sources—namely, environmental errors, errors that are dependent on the method, and errors typically encountered in Interferometry.

Measurement of small phase shifts using a single-mode optical-fiber interferometer

TL;DR: In this paper, periodic phase changes in the 10−6 -rad region were induced and detected in a single-mode all-fiber Mach-Zehnder interferometer by stretching the fiber with a piezoelectric cylinder driven at frequencies between 40 and 10−4 Hz.

An overview and a contribution to the optical measurement of linear displacement

TL;DR: In this paper, a brief overview of some existing solutions is presented and two systems for axial linear displacement measurement based on light intensity detection are introduced. The systems have redundancy and were designed with the purpose of achieving identification and automatic correction of errors arising from inadvertent angular variations between the sensor and the light beam positions.

The design of fiber-optic filters

TL;DR: A new design methodology is presented to realize an arbitrary filter as a difference of two positive filters, thus overcoming any performance limitation iniber-optic filters.

Analysis of etching-induced birefringence changes in elliptic core fibers.

TL;DR: A mathematical model is presented that predicts birefringence changes in an optical fiber as the cladding is removed and it is shown that this model approximates a highly elliptical fiber core with a rectangular dielectric waveguide.

Photosensitivity in optical fiber waveguides: Application to reflection filter fabrication

TL;DR: In this paper, the observation of photosensitivity in Ge-doped core optical fibers is reported. The photosensitivity is manifested by light-induced refractive index changes in the core of the waveguide.

Polarization optics of twisted single-mode fibers

TL;DR: In twisted single-mode optical fibers the polarization of light is affected by an elastooptically induced optical activity and by a modification of any linear birefringence present.

Single-mode fibre fractional wave devices and polarisation controllers

TL;DR: In this article, the authors describe new single-mode fiber optic devices which are completely equivalent to fractional wave plates of classical optics and employ a very simple configuration which uses the stress birefringence induced by bending the fibre.

Elimination of drift in a single-mode optical fiber interferometer using a piezoelectrically stretched coiled fiber

TL;DR: The feasibility of maintaining a single-mode optical fiber interferometer in quadrature is demonstrated using a servo driven piezoelectrically stretched coiled fiber with stress voltage coefficient of ~27pi rad/V.

All-fiber acousto-optic frequency shifter

TL;DR: An all-fiber-optic frequency shifter is demonstrated that uses mode coupling between the LP(01) and LP(11) modes by a traveling acoustic flexural wave guided along the optical fiber.
