Polarization insensitive measurement of the fiber-optic non-linear refractive index

, 1996
A novel cross-phase modulation scheme that permits measurement of the optical Kerr coefficient in nonpolarization-preserving fiber is presented. The scheme is based on a Michelson-type interferometer in which one mirror is replaced by an orthoconjugated ...

Polarization-insensitive four-wave-mixing-based wavelength conversion in few-mode optical fibers

We report theoretical and experimental results on a wavelength converter based on inter-modal phase-matching in a graded index three-mode elliptical-core fiber.

High-sensitivity terahertz sensor based on four-nested ring metasurface absorber

Journal of Measurement Science and Instrumentation
Terahertz (THz) waves exhibit distinctive advantages for biomedical sensing, while metasurface technology offers an effective route toward high-performance THz sensors. A high-sensitivity THz metasurface absorber sensor for biological sample detection is

The Research on Large-Mode-Area Anti-Bending, Polarization-Insensitive, and Non-Resonant Optical Fibers

In this paper, we propose a novel type of hollow-core anti-resonance fiber (HC-ARF). The cladding region of this fiber is formed by a combination of nested tubes and U-shaped tubes, and the centrally symmetric arrangement significantly reduces ...
