Refractive Index Profile Of Optical Waveguides Research Articles

A near-field method to recover the refractive-index profile of optical waveguides

A method to calculate the refractive-index profile of planar waveguides from near-field measurements is described. The method is based on a profile expansion in terms of orthonormal functions. Numerical simulations carried out on a symmetrical waveguide show that few-term expansions provide a satisfactory profile recovery. © 2000 John Wiley & Sons, Inc.

Comments, with reply, on 'Determination of two-dimensional optical waveguide index distribution function parameters from effective indexes' by T. Shiozawa et al

See T. Shiozawa, ibid., vol.8., p.497, 1990. Comments are made affecting the claim that the method proposed in the above-named paper of determining the refractive-index profile of optical waveguides from the effective indexes is more practical than other methods including that of the commenter. The author's reply gives a basis for verifying the original statement that this method is an improvement over others.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
