Low bend loss in tightly-bent fibers through adiabatic bend transitions
Optics Express, 2009 We demonstrate low bend loss for tightly bent optical fibers by winding the fiber around a mandrel designed to follow an adiabatic transition path into the bend. Light in the fundamental core-guided mode is smoothly transferred to a single cladding mode of the bent fiber, and back to the core mode as it leaves the bent region again.

Advanced Engineering Materials, EarlyView.Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Bending loss in optical fibers - a full-wave approach
, 2007 The radiated power emanating from a bent single-mode fiber is computed for various radii of curvature by a full-vectorial analysis. The only approximation is the truncation of a spectral series, the accuracy of which can be controlled. Hence, the complex
