Recovery of the refractive-index profile from the Wigner distribution of an optical waveguide

摘要

We propose a new method for the recovery of the refractive-index profile of a single-mode or multimode optical guided structure. We solve the inverse problem using the WiEner distribution and reduce it to the solution of a linear system of equations. # 1998 Optical Society of America OCIS codes: 100.3190, 130.0130, 230.7370, 000.3860.
