Bv. Gisin et Aa. Hardy, EIGENVALUE ANALYSIS OF GRADED-INDEX NONLINEAR-OPTICAL ANTIWAVEGUIDE, Journal of nonlinear optical physics and materials, 5(3), 1996, pp. 575-578
Stability regions of graded index nonlinear optical antiwaveguides are
numerically investigated. It is shown that as the antiwaveguide bound
ary between the core and cladding grows steeper, the structure becomes
more effective from the viewpoint of stability of the propagating mod
