The technological aspects and researches results of single - mode fiber polarizer are described. Single - mode fiber has been polished and covered with metalic layer for undiserable polarization mode attenuation. The extinction ratio range from 10 to 28 dB was obtained at λ = 0.63 and 0.85 µm.

With the increasing importance of monomode fibers, considerable thought has been devoted to design optimization. For telecommunications the technical goal of this work has been the simultaneous minimization of all forms of loss and dispersion over the widest possible wavelength region and with the broadest tolerance on key fiber parameters.

Single-mode-fiber birefringent filters
Optics Letters, 1980It is proposed to utilize optical birefringence in single-mode fibers for construction of wavelength-dependent filters. The birefringence may be natural (a consequence of the drawing process) or induced through external stresses. In the latter case, simple variation of these stresses may be used to tune the filter transfer function.

Single mode optical fiber sensors
1995Single mode fibers are used for sensing when extreme sensitivity is required or when a well defined polarization of light is needed at a remote sensing point. Most sensors which use single mode fibers are of the intrinsic type (i.e. the action of the measurand on the light occurs within the fiber itself). The sensitivity advantage of single mode fibers

Issues in single-mode fiber standardization
Fiber and Integrated Optics, 1984Abstract A review is given of the main organizations responsible for optical fiber standards activities, followed by a general discussion of specifiable characteristics of single-mode fibers and test methods for measuring them. The parameters and methods are then discussed in detail, with areas of disagreement among standards groups pointed out and ...

Single-mode fiber measurements
Optical Fiber Communication, 1987We review recent advances in the field of single-mode fiber measurements, pointing out the most promising developments. Although well-established techniques are already available for the most relevant parameters, there is still room for substantial improvement in terms of dynamic range, accuracy, and practicability of existing methods.

As shown by Marcuse,1 the fields of a single-mode fiber near cutoff are approximately Gaussian. Splice loss can, therefore, be calculated by evaluating the coupling between misaligned Gaussian beams. Based on this analysis, Nemoto and Makimoto2 derived a general equation for splice loss between nonidentical single-mode fibers with combined transverse x,

Seventh Topical Meeting on Integrated and Guided-Wave Optics, 1984
Optical fibers were once thought of strictly as a transmission medium. It was expected that any processing of the optical signal would take place outside of the fiber; either by conventional electronics, or by devices based on planar integrated optics.

Single-mode fiber measurements
Optical Fiber Communication, 1983This paper will discuss the measurement of those optical performance properties that are unique to single-mode fibers; chromatic dispersion; cutoff wavelengths associated with the fundamental and higher-order modes; and mode diameter or spot size. I shall review the various techniques available for measuring these properties and emphasize those that ...
