Abstract
The analogy between optics and quantum mechanics is exploited by considering a 2-D quantum system The Schroediner equation is closely related to the wave equation for light propagation in an optical fiber. whose From this viewpoint, Marcatili’s condition for minimal-dispersion-refractive-index profiles, and the Olshan-formula for rms pulse spreading in an α-profile fiber may be derived without recourse to the WKB sky-Keck approximation. Besides affording physical insight into these results, the present approach points out a possible limitation in their application to real fibers.
