All Solid Multistep-Index Core Large Mode Area Single-Mode Fiber
IEEE Photonics JournalIn this paper, a large-mode-area (LMA) single-mode fiber based on multistep-index core structure is proposed. The multistep-index core increases the mode field area (MFA).

Pediatric Blood &Cancer, EarlyView.ABSTRACT Surveillance imaging aims to detect tumour relapse before symptoms develop, but it's unclear whether earlier detection of relapse leads to better outcomes in children and young people (CYP) with medulloblastoma and ependymoma. This systematic review aims to identify relevant literature to determine the efficacy of surveillance magnetic ...

Modelling and Simulation of a Rectangular Large Mode Area Photonic Crystal Fiber [PDF]
EPJ Web of ConferencesThis work presents a rectangular large core area (R-LCA) PCF with a cladding diameter of 125 µm, a pitch of 9 µm, and a hole diameter of 8 µm. The guided modes were obtained through numerical simulations using COMSOL Multiphysics.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Psychological safety (PS) is essential for teamwork, communication, and patient safety in complex healthcare environments. In pediatric oncology, interprofessional collaboration occurs under high emotional and organizational demands. Low PS may increase stress, burnout, and adverse events.

Bending Orientation Insensitive Large Mode Area Photonic Crystal Fiber With Triangular Core
IEEE Photonics Journal, 2013 In view of the feasibility of fabrication and application, a bending orientation insensitive large mode area photonic crystal fiber with triangular core is proposed. This fiber structure breaks the limit of bend orientation angle and realizes single mode

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

Bending performance of large mode area multi-trench fibers
Optics Express, 2013 Bending performance of the Multi-trench Fibers (MTFs) has been investigated using the Finite Element Method. Numerical investigations show that MTFs can provide low-loss effective single mode operation under bent configuration, thanks to the resonant coupling of the Higher order Modes (HOMs).

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Black Phosphorus Q-Switched Large-Mode-Area Tm-Doped Fiber Laser
International Journal of Optics, 2018 We report on a passively Q-switched fiber laser with black phosphorus as saturable absorber. By employing the sol-gel fabricated large-mode-area Tm-doped fiber as gain medium, a high-energy Q-switched fiber laser has been demonstrated which delivers the ...
