Single-Polarization Single-Mode Hollow-Core Anti-Resonant Fiber
We propose a novel hollow-core anti-resonant fiber (HC-ARF) with double tangent circular arc tubes (CATs) for robust single-polarization single-mode (SPSM) operation.
Polarization-Maintaining Single Mode Optical Fiber
This polarization-maintaining fiber is optimized for fiber optic gyroscope (FOG) applications. It is designed for optimal performance over a wide temperature range and with a small coil radius.
Single-Polarization Single-Mode Hollow-Core Anti-Resonant Fiber with
The high refractive index of the single-ring tubes enables the y -polarization mode to maintain low loss over a wavelength range exceeding 1000 nm, without affecting the high-loss

Today, we''re expanding what Microsoft 365 Copilot can do with GPT-5.5 Thinking and ChatGPT Images 2.0 bringing stronger support for deeper analysis, multi-step work, and visual
Single-Polarization Single-Mode Hollow-Core Anti-Resonant Fiber with
A novel single-polarization single-mode double-ring hollow-core anti-resonant fiber with two single-polarization regions (1545–1553 nm and 1591–1596 nm) is proposed.
Single-polarization single-mode broadband ultra-low loss hollow-core
A novel five-tube nested double C-type single-polarization hollow-core anti-resonant fiber (HC-ARF) is proposed for single-polarization single-mode, ultra-low loss, and broadband
