Single-mode optical fiber cable

Applied Optics, 1979
A single-mode optical fiber cable was manufactured; loss increase characteristics due to cabling were evaluated. The existence of wide V-value regions without cabling loss increases is shown by a suitable selection of fiber parameters and optical wavelengths.

Single-mode polymer optical fibers

2014 16th International Conference on Transparent Optical Networks (ICTON), 2014
The mechanical properties of polymer optical fibers (POF) make them very interesting candidates for fiber optical sensors. Today POFs are mainly used for short range data communication. These fibers have a very large core of 980 μm. This large core is beneficial for handling and maintenance in fiber networks.

Single-mode optical fiber goniometer

Optics Letters, 1992
A two-element single-mode optical fiber goniometer that uses graded-index microlens receivers is presented that measures the angular orientation of a remote laser. The goniometer exhibits a sensitivity of 1.0 V/mrad and a calculated shot-noise-limited angular resolution of 1.0 nrad/ radicalHz.

All Single Mode Fiber Optic Gyroscope

Optics Letters, 1981
We present an optical fiber gyroscope that, for the first time, is composed completely of single-mode fiber-optic components. This system has increased simplicity and stability over previous bulk-optic designs and has the potential for very high rotation sensitivity.

Fiber optic gyroscope with single mode fiber coil

8th Optical Fiber Sensors Conference, 1992
Fiber optic gyros (FOGs) are all solid state devices, compact, lightweight and highly reliable. These merits have attracted much attention and developments have been energetically implemented mainly for aerospace applications.

Nonmechanical optical switch for single-mode fibers

Applied Optics, 1982
This paper introduces a bistable nonmechanical optical switch for single-mode optical fibers. A l-input/2-output device for the l-microm wavelength range, the optical losses of the switch are independent of the polarization state in the input fiber. The insertion losses for the optical signal from the input fiber to the output fiber are 1.4 dB and the ...

Single-mode fiber-optic directional coupler

Applied Optics, 1982
A low-loss compact single-mode fiber optical directional coupler (SMF-ODC) is developed for use in SMF reflectometers or gyroscopes. The SMF-ODC is made of two sapphire ball lenses, a half-mirror, and two ferrules. Two fibers (endfaces are concave) are aligned parallel to each other in the ferrule. The optical and mechanical axes are tilted. Cross-talk

Polarization optics of twisted single-mode fibers

Applied Optics, 1979
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. These effects are discussed theoretically and demonstrated experimentally. The activity/twist ratio is alpha/tau approximately 0.13 ...

Coupling starlight into single-mode fiber optics

Applied Optics, 1988
We have calculated the efficiency with which starlight can be coupled into a single-mode fiber optic that is placed in the focal plane of a telescope. The calculations are performed for a wide range of seeing conditions, with and without rapid image stabilization, and for a wide range of wavelengths. The dependence of coupling efficiency on the f-ratio

Single-mode optical fibers in the visible range

Journal of Lightwave Technology, 1991
The fabrication and characterization of single-mode optical fibers in the visible range are discussed. The small core size is obtained by etching the core layers with a flux of freon during the collapse of the preform. The modifications of the index profile are attributed to diffusion of germanium and to incorporation of freon during collapse. From the
