Abstract

A multimode planar optical waveguide of homogeneous refractive index can produce real one-dimensional self-images by interference of the waveguide modes. We discuss the image formation, the linespread function, and its apodisation and optimization. Under optimum conditions, the theoretical linear resolution can reach 0.25(W λ_f)^1/2, where W is the slab thickness and λ_f is the wavelength in the slab material.
