Abstract

The spectrum of modal cut-off wavelengths is studied for waveguides with step and graded index profile. It is shown that by measuring the cut-off wavelength of supported modes it is possible to obtain values for the refractive index of the guiding layer in the step-index case, and information on the diffusion length and the best profile shape for graded-index guides. This method has been experimentally applied to InGaAsP and InGaAlAs waveguides, whose indices are obtained with accuracy to the third decimal place, in favorable comparison to other techniques, and to Ti:LiNb0₃ guides.
