A new, rigorous analytical theory for obtaining electromagnetic fields in circular bends of slab waveguides is presented. The theory is applied to the problem of Gaussian beam incidence upon the uniformly curved sections of dielectric slab waveguides from the outside region. The field distribution change as the beam wave propagates is looked into and the power coupled into the guided wave is evaluated.
