High-performance single-mode fiber-optic switch
Optics Letters, 1994A piezoelectrically actuated four-port Mach-Zehnder switch with 30-micros switching time and 0.25-dB insertion loss is demonstrated at a wavelength of 1.3 microm. The worst-case cross talk is below -21 dB for an arbitrary input polarization. The process of fabricating the switch from commercial fiber couplers with length matching of the interferometer ...

Experimental investigation of single-mode single-polarization optical fiber
Optics Letters, 1992An experimental study of the polarization properties of single-mode optical fibers of differential polarization-mode attenuation is presented. The output state of polarization was measured at various input polarization orientations and wavelengths. The transition from a two-polarization to a single-polarization regime of operation was investigated ...

Single-mode fiber-optic directional couplers
Fiber and Integrated Optics, 1987Abstract A new design of Y-type end-fused single-mode fiber directional couplers has been suggested and its optimum parameters to obtain losses of 0,5–1 dB have been determined. A technique has been developed for fabricating such couplers by electric arc fusion of single-mode fibers with thin claddings.

Single-mode optical fiber liquids analyzer
SPIE Proceedings, 2010We propose a single-mode optical fiber sensor for characterization of physical and chemical properties of liquids. The sensor is based on monitoring changes in the back-reflected signal from the interface between the fiber end-face and the liquid sample.

Single-mode optical fiber antennas
SPIE Proceedings, 1990The purpose of this paper is to calculate the radiation from bent single-code optical fibers along arbitrarily oriented curved shape, which we call 'single-mode optical fiber antennas' (SMOFA). A generalized voluie current cethod (VCM) is used in order to determine the radiated power of a N-iultiturn optical fiber antenna in the fore of circular ...

Transparent single-mode fiber optical networks
Journal of Lightwave Technology, 1986For the first time in the history of communications technology, single-mode fiber offers the possibility of truly transparent communications systems. In this paper we consider the application of single-mode fiber technology to optical networks and the evolution of the technology to all optical networks based on space or wavelength switching.

Efficient single-mode fiber-optic module
Soviet Journal of Quantum Electronics, 1989A study was made of the optimal conditions for coupling a laser beam (λ = 1.3 μm) with a slight ellipticity of its transverse cross section into a single-mode fiber waveguide. The coupling was performed by a hemispherical microlens formed from a cone-tapered end of a fiber waveguide. The maximum coupling efficiency achieved in these experiments was 78%,
