Abstract

Practical device implementations of non-linear waveguides may utilise the defocussing non-linearity associated with the fundamental absorption edge of semiconductors. A suitable slab waveguide structure would involve a non-linear guiding layer bounded by cladding layers which are non-absorbing and hence linear at the operating wavelength. An analysis of TE modes in such a structure is given for the first time in this paper.
