Radiation effects in polarization-maintaining fibers

Optical Fiber Communication Conference, 1989
One likely application for polarization-maintaining (PM) fiber is in fiber-optic gyroscopes onboard spacecraft. Severe performance degradation could occur if the PM fiber is sensitive to the space radiation environment, which depends on such factors as the spacecraft orbit, shielding by the skin and structure, and sunspot activity.

Polarization-Maintaining Fibers

Applied Scientific Research, 1982
The parameters that determine the polarization-maintaining ability and the polarization-dispersion of a birefringent fiber are discussed in a tutorial fashion. Based on promising theoretical and experimental results, I conclude that fibers with adequate polarization-maintaining properties for sophisticated heterodyne and homodyne applications are ...

Polarization-maintaining fibers and their applications

Journal of Lightwave Technology, 1986
Polarization-maintaining fibers and their applications are reviewed. The classification of high-birefringent fibers and low-birefringent fibers and their fabrication methods and characteristics are discussed in Section II. Analytical methods and numerical methods for fiber design on the birefringence are presented in Section III. Degradation factors of

Method for fusion splicing polarization-maintaining photonic crystal fibers and conventional polarization-maintaining fiber

AOPC 2019: Optical Fiber Sensors and Communication, 2019
In view of mode field matching problem between the polarization-maintaining photonic crystal fiber and the conventional optical fibers, the polarization and mode field distribution characteristics of photonic crystal fiber were analyzed and investigated by using a finite element method.

Update on polarization-maintaining fibers

Optical Fiber Communication, 1984
There is widespread interest in fibers which can hold a given state of polarization despite bends, kinks, and environmental changes. Applications at present are primarily in fiber sensors with the fiber gyroscope1 the most immediate. However, the attainment2 of low loss with good polarization holding in lengths up to 8 km is an indication of the ...

Polarization-maintaining and absorption-reducing fibers

Optical Fiber Communication, 1982
Single-mode and low-loss optical fibers maintaining a state of polarization over a long length are necessary for coherent optical communication and fiber-optic sensing systems.1 Stress-induced birefringence fibers as reported so far show the high losses.2 Polarization mode dispersion (PMD) of these fibers is measured to be of the order of 50300 psec/km,

Polarization-Maintaining Optical Fibers

1989
In ordinary axially symmetrical single-mode fibers, two mutually independent orthogonal HE11 modes can propagate. In the framework of Cartesian coordinates, these are the HE11x mode, which has its principal electric field component in the x direction, and the HE11y mode, which has principally the y component of the electric field. We hereafter omit the

All-Polarization-Maintaining Ultrafast Fiber Lasers

Optical Fiber Communication Conference (OFC) 2025
Utilizing a self-stabilized interferometer mode-locker, we demonstrate a bidirectional all-polarization-maintaining Er-doped fiber laser, and the generation of both harmonic mode-locking and noise-like pulses in an all-polarization-maintaining Tm-doped fiber laser.

Practical circular-polarization-maintaining optical fiber

Applied Optics, 1997
The author describes a new idea for making circular-polarization-maintaining optical fiber with an existing fabrication technique. The method simply requires one to spin at a constant rate a special preform consisting of only one off-axis stress-applying element in addition to the on-axis core.

Developments in Elliptical Core Polarization-Maintaining Fiber

8th Optical Fiber Sensors Conference, 1992
Polarization maintaining (PM) optical fibers are showing promise in a new generation of gyroscope applications and other fiber optic sensing systems. One of the key obstacles to making in-roads in these applications remains the longterm cost of the PM fiber.
