Helical Long-Period Gratings Inscribed in Polarization-Maintaining Fibers by CO2 Laser

Journal of Lightwave Technology, 2019
We demonstrate the fabrication of helical long-period gratings (HLPGs) in a polarization-maintaining fiber using a CO2 laser. The maximum polarization-dependent loss (PDL) of the grating was measured to be more than 30 dB at the resonance wavelength. The

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 ...

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 near‐field optical probes

Journal of Microscopy, 2008
SummaryWe demonstrate that tapered optical fibre probes can be easily modified in the taper cone to realize an electric dipole producing a well‐defined near‐field polarized light. This novel structure is made of a Short‐cut Double C–shaped probe design combined to the usual full metal coating near the tapered end of the fibre.

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

Plant cell biology: PIN polarity maintained

Current Biology, 2021
PIN-FORMED (PIN) polar protein localization directs transport of the growth and developmental regulator auxin in plants. Once established after cytokinesis, PIN polarity requires maintenance. Now, direct interactions between PIN, MAB4/MEL and PID proteins suggest self-reinforced maintenance of PIN polarity through limiting lateral diffusion.

Low-loss polarization-maintaining hollow-core anti-resonant terahertz fiber

Journal of Optics, 2019
Polarization-maintaining terahertz (THz) fibers have been considered as fundamental elements in polarization sensitive THz systems. Based on the anti-resonant waveguiding mechanism, we propose a low-loss polarization-maintaining hollow-core THz fiber ...
