Journal ArticleDOI
Coupled mode theory of parallel waveguides
Amos A. Hardy,W. Streifer +1 more
TL;DR: In this paper, a coupled mode formulation for parallel dielectric waveguides is described, and the results apply to any guided modes (TE, TM, or hybrid) in waveguide of arbitrary cross-section, dissimilar index, and non-identical shape.
Journal ArticleDOI
Strongly pumped fiber lasers
I. Kelson,Amos A. Hardy +1 more
TL;DR: In this paper, the authors analyzed strongly pumped fiber laser systems based on a rate equation model and showed that approximate analytical and quasi-analytical expressions are in excellent agreement with the exact numerical solution of the rate equations, and both agree well with recently published experimental data.
Journal ArticleDOI
Signal amplification in strongly pumped fiber amplifiers
Amos A. Hardy,R. Oron +1 more
TL;DR: Signal amplification in strongly pumped fiber amplifiers was analyzed in this paper for three-level and four-level transitions, including scattering loss and excited state absorption, and simple analytic expressions were derived for the signal amplification and pump attenuation, along the fiber length.
Journal ArticleDOI
Modes of periodically segmented waveguides
Z. Weissman,Amos A. Hardy +1 more
TL;DR: In this article, the modal properties of periodically segmented waveguides (PSWs) were analyzed by using the beam-propagation method and coupled-mode theory, and the results can be applied to the design of waveguide devices such as two-dimensional mode tapers and frequency selective couplers.
Journal ArticleDOI
Optimization of strongly pumped fiber lasers
I. Kelson,Amos A. Hardy +1 more
TL;DR: In this paper, a rate equation model was introduced and studied for Yb/sup 3+/-doped fiber laser, with DBR mirrors at either end, and an approximation analytical and quasi-analytical expressions were obtained in excellent agreement with the exact numerical solution of the rate equations.
