Cladding mode coupling in highly localized fiber Bragg gratings: modal properties and transmission spectra

, 2010
The spectral characteristics of a fiber Bragg grating (FBG) with a transversely inhomogeneous refractive index profile, differs con- siderably from that of a transversely uniform one.

Quantitative Mapping of Fibrotic Tissue Mechanics via Brillouin Spectroscopy

Journal of Biophotonics, EarlyView.
Brillouin spectroscopy distinguishes fibrotic from healthy tissue based on localized stiffness changes and enables real‐time monitoring of dynamic alterations in viscoelastic properties during fibrogenesis. ABSTRACT Fibrosis is a pathological scarring process that disrupts tissue architecture, and is characterized by excessive extracellular matrix (ECM)
