Numerical Analysis of Optical Fiber Refractive Index in the Miniaturized Graded‐Index Fiber Probe
Engineering ReportsWe analyze the impact of the refractive index of optical fibers on the focusing properties of a miniaturized graded‐index (GRIN) fiber probe. The ABCD ray transfer matrix and characteristic parameters are employed to characterize the working distance ...

An index theorem in differential K-theory [PDF]
, 2010 Let X --> B be a proper submersion with a Riemannian structure. Given a differential K-theory class on X, we define its analytic and topological indices as differential K-theory classes on B.

Theory of cw Raman oscillation in optical fibers [PDF]
, 1979 A theory for Raman fiber laser oscillators is presented. The Stokes output and the residual pump power are shown to be calculable from a knowledge of the input pump power and the fiber characteristics. The evolution of the pump and the Stokes waves along

Optimal pulse propagation in an inhomogeneously gas-filled hollow-core fiber
, 2019 We study optical pulse propagation through a hollow-core fiber filled with a radially inhomogeneous cloud of cold atoms. A co-propagating control field establishes electromagnetically induced transparency.

Unidirectional mode coupling in graded index fibers
13th International Conference on Metamaterials, Photonic Crystals and Plasmonics (META 2023): July 18-21, 2022 2023, Paris, France (Poster Presentation)., 2023 Unidirectional mode coupling in graded index fibersWe propose a new light management mechanism in parabolic index multimode fibers to control the mode distribution of the propagatedbeam. The effect is achieved through longitudinal non-Hermitian potential induced by simultaneous modulations of the index andgain/loss profile. The non-Hermitian modulation
