الملخص الإنجليزي

Graphene is a single layer of covalently bonded carbon atoms, which was discovered at the last decade.

It has electronical transport and optical properties so that it is unusual material it yet has already attracted intense research.

In this work, a three layer waveguide sensor is proposed.

The structure consists of an infinitesimally sheet of thin conducting graphene material layer which is followed by dielectric layer and a substrate layer of kerr-like nonlinear medium.

The dispersion relation of such a structure is derived in terms of the thickness and the physical parameters.

The dispersion relation for the waveguide structure for transverse electric (TE-Mode) wave and nonlinear equation were also investigated.

The sensitivity of the effective refractive index to variations in the refractive index of the cladding is obtained.

Sensitivity has been obtained by tuning some physical parameters.

This thesis has concluded that the proposed sensor gave results for the sensitivity.

The results are very important and useful for the practical application of graphenebased optoelectronic sensors.
