Frequency characteristics of graded-index fibers

Applied Optics, 1980
Frequency response of graded-index multimode fibers, whose index profile parameter alpha deviates from the optimum value, is investigated both theoretically and experimentally. The frequency response of the fiber with optimum alpha diverges periodically.

Pulse broadening in graded-index optical fibers

Applied Optics, 1976
This paper reports on some theoretical and experimental investigations of the radial refractive index gradient that maximizes the information-carrying capacity of a multimode optical waveguide. The primary difference between this work and previous studies is that the dispersive nature of core and cladding materials is taken into consideration.

Refracting leaky rays in graded-index fibers

Applied Optics, 1978
A local plane wave analysis is employed to derive the ray power transmission and attenuation coefficients for refracting leaky rays on graded-index fibers. These coefficients also reduce to established forms for tunneling rays and are compared with modal attenuation coefficients in the limit of strongly refracting rays.

Graded-index characteristics in single-crystal fibers

Optics Letters, 1998
Single-crystal fibers of Ti(3+):Al(2)O (3)have been grown by the laser-heated pedestal growth technique and shown to exhibit radial refractive-index gradients. A refractive-index increase of approximately 12% in the fiber core with respect to the fiber sidewalls has been measured. The index profile can be fitted with a parabolic model.

Light propagation in graded-index optical fibers

Applied Optics, 1978
An accurate numerical method is described for solving the Helmholtz equation for a general class of optical fibers. The method yields detailed information about the spatial and angular properties of the propagating beam as well as the modal propagation constants for the fiber.
