Elliptical hollow-core optical fibers for polarization-maintaining few-mode guidance

Optical fiber technology (Print), 2019
We propose polarization-maintaining few-mode elliptical hollow-core optical fibers with simple triple-layer structure toward space-division-multiplexing based high-capacity optical communication systems.

Vernier effect of fiber interferometer based on cascaded PANDA polarization maintaining fiber

Chinese Optics Letters (COL), 2019
This Letter shows the Vernier effect based on two segments of PANDA polarization maintaining fiber (PMF), whose lengths are 28 and 23 cm, respectively. The two PMFs are spliced together, and the angle between the fast axes is set to 45°.

Radiation induced attenuation in pure silica polarization maintaining fibers

Journal of Non-Crystalline Solids, 2019
Radiation-induced attenuation (RIA) at λ = 1.55 μm is studied in polarization-maintaining (PM) pure-silica-core optical fibers of the Panda-type under γ-irradiation and upon pulsed-X-ray-irradiation. For the first time, the RIA spectrum is compared under

Fiber Devices Using Polarization-Maintaining Fibers

SPIE Proceedings, 1987
Abstract Fiber devices using polarization-maintaining fibers called PANDA fibers are presented. They are polarization-maintaining couplers and polarization-splitting couplers, optical isolators and optical circulators, and multi/demultiplexers designed for 1.3 μm wavelength. Crosstalk of-32 dB and excess loss of 0.03 dB for the polarization-maintaining

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.

Polarization-maintaining photonic bandgap Bragg fiber

Optics Letters, 2009
The possibility of fabricating a polarization-maintaining Bragg fiber has been studied. It is shown that violation of the cylindrical symmetry of a Bragg mirror in most cases results in a sharp increase in optical loss, which is caused by resonance transmission through the Bragg mirror at wavelengths near the cutoffs of the modes of the high-index ...
