Abstract

In this report we propose single beam holographic scheme for formation of focusing grating, designed for different purposes, on the waveguide surface. The main idea is to substitute the traditional flat mirror with one of nonplane surface. Different surfaces correspond to two cases involved. (1) Plane wave propagating in the waveguide is coupled out into the air and focused into a spot. Appropriate relations for geometric parameters of the sphere have been developed. Experimental verification has shown that diffraction-limited focusing spot can be achieved for grating length to focal length ratio l/f < 0.1. (2) External incident plane wave is coupled in and focused by the grating inside the waveguide. It is shown that aberration-free grating can be formed using a conical surface as the mirror. Simple formulas for geometric parameters are also presented. Focusing of an He-Ne laser beam ((lambda) equals 1.15 micrometers ) in a waveguide plane is demonstrated.
