Buying Hollow-core Fibers

Guiding Photonics fabricates hollow core fibers with a metallic reflective coating on the inner side of a hollow glass or plastic tube. For infrared transmitting fibers, there is also a dielectric layer with a thickness optimized for a specific wavelength range.

Explore the distinctive hollow-core photonic crystal fiber technology, guiding light within a hollow channel and enveloped by a microstructured cladding. A unique approach that redefines precision and efficiency in the field of photonics.

As a trailblazing industrial leader, GLO takes the forefront in photonics with a diverse array of hollow-core photonic crystal fiber solutions, tailored to meet the unique needs of our valued partners. Our commitment lies in delivering bespoke HCPCF innovations, setting new standards in the industry.

Optical signals in a hollow core photonic bandgap fiber are guided in an air core surrounded by a PBG microstructured region. In addition to the low bend sensitivity, this fiber design exhibits significantly reduced material nonlinearities since more than 95% of optical power is propagating in air. In addition, air/undoped silica provides excellent temperature immunity, which is critical for high performance fiber sensing and metrology applications.

Optical signals in a hollow core anti-resonant fiber propagate in an air core surrounded by a single ring of anti-resonant tube elements. Guidance is based on an anti-resonance from the thin glass membranes constituted by the non-touching tubes surrounding the hollow core. The extremely low overlap of guided power with the surrounding silica, less than 2 · 10⁻⁵, in addition to the large effective mode area, leads to a record-low optical nonlinearity.

The new few-cycle flexible hollow core fiber system allows you to choose various fiber lengths and inner diameters to achieve a desired nonlinear effect. Experimentally measured transmission for multi-mJ femtosecond pulses ranges between 50% and >90%, depending on the application.

The most versatile choice for laser pulse post compression: The few-cycle hollow core fiber supports input energies from 50 μJ to 100 mJ, up to 20 times compression and transmission >90% while keeping the footprint and optical path length at a minimum.

Solutions for Innovators

Hollow-core photonic bandgap fibers turn conventional fiber technology inside out by guiding the light in a hollow-core. This unique waveguide is ideal for sensing, imaging, and ultrashort pulse applications. Our hollow-core photonic bandgap fibers deliver ultrashort pulses without non-linear effects or material damage and tolerate tight bending without impact on transmission. Hollow-core fibers are radiation insensitive and suitable for harsh radiation environments.

YOUR KEY to innovation and success

UltraFast Innovations (UFI®) manufactures complete hollow-core fiber compressors to compress high-energy ultrashort pulses by nonlinear spectral broadening in a gas within the hollow-core fiber and subsequent compression with chirped mirrors.
