Φ80μm polarization-maintaining fiber coupler for fiber optic gyroscope
SPIE Proceedings, 2008The polarization-maintaining fiber coupler (PMFC) is a kind of optical coupler manufactured with polarization-maintaining fiber (PMF). It is the pivotal device to realizing the linearly polarized light coupling, the dispersion of light as well as the multiplying.

Phase modulation of an electro-optic polymer cladded polarization-maintaining optic fiber
Optics Letters, 2008We present, for the first time based on our knowledge, a novel in-fiber optical phase modulator that is inherently broadband, efficient, and polarization-maintaining (PM). The modulator is a 25 mm long section of a D-shaped cladding PM fiber with half of its silica cladding replaced with an electro-optic (EO) silicone gel.

Polarization-maintaining optical fibers with hollow circular pits
Journal of Lightwave Technology, 1986This paper gives a detailed investigation on the polarization-maintaining optical fibers with one hollow circular pit across the core-clad interface (single circular-pit fiber (SCF)), and two hollow circular pits across the core-clad interface (double circular-pit fiber (DCF)).

Angular alignment of a polarization-maintaining optical fiber
Optical Engineering, 2001We describe a simple, fast, and accurate technique for the angular alignment of a polarization-maintaining monomode optical fiber. The method uses simple mechanical supports and is based on the de- tection of the ellipticity of the light polarization at the fiber output, with the help of a simple rotating polarizer, a photodetector, and an oscilloscope.

Optical Intrusion Detection Sensor with Polarization Maintaining Fiber
1st Workshop on Specialty Optical Fibers and Their Applications, 2008An optical intrusion-detection sensor based on a Sagnac interferometer has been developed for fence-mounted perimeter security applications. The interferometer is completely made of polarization maintaining fiber and related components. This sensor has been adopted by some important institutions as part of their physical security systems.

Fiber gyroscope using a polarization-maintaining optical fiber and a fiber coupler
SPIE Proceedings, 1990A fiber gyroscope usin a polarization-maintaining optical fiber(PMF) has been studied. A phase shift of the laser beam passing through the PMF by an ultrasonic wave has been observed In this paper, the fiber gyroscope using the PMF and a polarization-maintaining fiber coupler(PMC) is presented.
