Hollow Photonic Crystal Fiber (HCPCF)

Hollow photonic crystal fiber is composed of two-dimensional photonic crystals arranged periodically, and the core is the air defect of hollow structure. Different from the total internal reflection light guide mechanism of traditional optical fiber, hollow photonic crystal fiber uses photonic bandgap effect to realize light transmission in air.

Most of the optical energy in the optical fiber (more than 95%) is transmitted in the air core, so the optical transmission is less affected by the absorption of optical fiber materials, excellent anti-radiation performance, good thermal stability, and has application advantages in harsh environment. With low nonlinear effect and delay and high damage threshold, it has obvious advantages in the flexible transmission of high power and pulsed laser, and can be used as an efficient platform for the interaction between light and matter.

In order to prevent moisture and dust from entering the hollow microtubule to affect the later performance, both ends of the polarization-maintaining photonic crystal fiber must be sealed.

Advanced Engineering & Technology Dynamics

Revolutionizing conventional solid-core transmission, our Hollow Photonic Crystal Fiber (HCPCF) represents a major leap in modern optical engineering. By leveraging the photonic bandgap effect instead of total internal reflection, over 95% of optical energy is confined within the air core. This architectural triumph fundamentally eradicates standard material absorption limitations, cementing it as the premier anti-radiation optical fiber capable of maintaining exceptional thermal stability across severely harsh environments.

This engineered internal microstructure not only guarantees a remarkably low nonlinear effect and minimal latency, but it also establishes an astonishingly high damage threshold. These parameters make our HCPCF the definitive medium for the flexible delivery of ultra-high power and pulsed laser transmission. Designed to cater to top-tier industrial demands, it is currently the platform of choice for cutting-edge fiber optic sensing, highly precise fiber optic gyroscopes, nonlinear optics experimentation, and high-fidelity data communication networks.
