Paper Abstract

The optical grating has been the subject of extensive, sustained research for many years. Field of their application include integrated optics, quantum electronic, holography, and spectroscopy. Grating functions include laser-beam feedback, distributed Bragg reflection, holographic beam combining, wavelength multiplexing, wavelength de-multiplexing, and others. Another interesting object of modern physical research is a layer of a resonant plasma (LRP) in which if the charge equilibrium of this system is distributed, the electron gas performs density oscillations, the so-called plasma oscillations and the complex refractive index of which is described by Dride's formula. It is the purpose of this work to combine this two interesting physical objects and investigate the process of the light diffraction by dielectric grating which enclose LRP. We researched Ge-grating on GaAs-substrate under the service of conversion almost vertically incident light into quasi-horizontally propagating light inside the substrate. It is common knowledge that process of conversion almost vertically incident light into quasi-horizontally propagating light is very interesting from the practical standpoint for many cases for example for introduction of light into different optical structure. In our investigation LRP was placed both in the Ge-grating region and in the region of GaAs-substrate.
