It is found that these different tapering profiles can support both bright and dark similaritons with significantly high intensity. In particular, we study the

Controllable Optical Similaritons in GRIN by Tailoring of Tapered Profile,near waveguide. By utilizing the isospectral Hamiltonian approach with the crucial observation that the equation governing the tapering profile can be transformed into a Schrödinger-like equation, we detail the procedure to tailor .-type and parabolic tapering profiles of such waveguides. We demonst
