Y. Satomura et Y. Muroi, PROPAGATION OF NONLINEAR-WAVES GUIDED BY PLANAR WAVE-GUIDES WITH INHOMOGENEOUS REFRACTIVE-INDEX PROFILE, IEICE transactions on electronics, E76C(10), 1993, pp. 1510-1514
The propagation characteristics of nonlinear TE waves guided by planar
optical waveguide whose guiding region has arbitrary inhomogeneous re
fractive-index profile are investigated theoretically by using the WKB
method. The effects of inhomogeneous index profile of a guided region
on the propagation characteristics such as the propagation constant a
nd the field distribution are estimated numerically.
