Low-loss multimoded antiresonant hollow core fiber

, 2020
We report the first design for low-loss, multimoded antiresonant hollow-core fiber for applications requiring multiple modes. The designed fiber guides 6 - 9 spatially distinct core modes having confinement loss \lt 0.001 -0.01dB/m respectively.Submitted/

Development of hollow-core photonic bandgap fibres free of surface modes

, 2009
Conventional optical fibres can only guide light in a high refractive index core by total internal reflection. By using total internal reflections it is not possible to guide light in an air core.

In-fiber polarimeters based on hollow-core photonic bandgap fibers

Optics Express, 2009
In-fiber polarimeters or polarization mode interferometers (PMIs) are fabricated by cascading two CO2-laser-induced in-fiber polarizers along a piece of hollow-core photonic bandgap fiber. Since the two interfering beams are the orthogonal polarizations of the fundamental mode, which are tightly confined to the core and have much lower loss than higher

A Low‐Cost, Handheld Optical Stiffness Sensor for Minimally Invasive Surgery

Advanced Robotics Research, EarlyView.
A novel handheld stiffness sensor is presented for real‐time tissue stiffness characterization. By simultaneously sensing contact force and tissue deformation, the device enables accurate stiffness quantification without requiring precise manual control. This approach offers a promising solution for intraoperative tumor detection and minimally invasive

Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

Advanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

Long period fiber gratings in anti-resonant hollow core fiber

Applied Physics Express
Long period gratings, based on anti-resonant hollow core fibers (AR-HCFs), are fabricated using a high-frequency CO _2 laser pulse by carving periodic grooves. This device exhibits both axial strain and bending sensing characteristics.
