With the use of the scalar field approximation a study has been made of a guide ha¨ing a shape of the lemniscate of Bernoulli as its cross section. This structure represents approximately the situation when two cores are embedded in the same cladding. This is often done in ( practice. In this case o

We make an analytical study of the modal cutoff beha¨ior of a wa¨eguide with an annular core cross section bounded by two nonconcentric circles. The characteristic and cutoff equations are obtained with the use of the weak guidance approximation. Numerical computations show that the number of modes
