Summary :

A method of calculating geometrical optics fields in dielectric tapered waveguides excited at the input ends by a monochromatic Gaussian beam light is presented. It is shown that field distributions expected at the output ends of waveguides can be determined without calculating fields at intermediate steps of propagation between the input and output ends. Examples of multimode propagation and monomode propagation in a linearly tapered waveguide are given.
