Single-mode optical fiber cable
Applied Optics, 1979A 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 optical fiber goniometer
Optics Letters, 1992A 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, 1981We 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.

Single-mode fiber-optic directional coupler
Applied Optics, 1982A 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

Single-mode fiber-optical polarization rotator
Applied Optics, 1979A birefringent single-mode optical fiber is twisted mechanically in alternating sense on successive half-wave fiber sections. This arrangement, applicable in-line to a fiber, permits continuous adjustment of the state of polarization at the fiber output.

Single-mode optical-waveguide fiber coupler
Applied Optics, 1978A single-mode fiber coupler to the Ti diffused LiNbO(3) strip waveguide has been devised. The influences of three axial displacements and two angular misalignments on the coupling efficiency have been investigated at 6328-A wavelength. The coupler has a special feature wherein coupling degradation caused by fiber displacement after connection can be ...

Optical field mapping using single-mode optical fibers
Applied Optics, 1978A new method of measuring the complete optical field distribution (optical field mapping) is proposed and is applied to the measurement of Gaussian beam distribution at its beam waist. This method utilizes an interference technique and uses two single-mode optical fibers as flexible paths.

Single-mode polymer optical fibers
2014 16th International Conference on Transparent Optical Networks (ICTON), 2014The 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.
