Abstract
This paper deals with the spectral properties of optical networks that consist of a single, distributed 3x3 coupler embedded in a feedback circuit. We first specify a set of coupled linear differential equations that characterize the coupler. The solution of this set of equations yields the scattering transfer matrix of the coupler from which, through linear transformation, we obtain its scattering matrix. Subsequently, we determine the scattering matrix of the composite network, i.e., the coupler, embedded in the external circuitry. Numerical experiments illustrate the properties of composite networks of various configuration.
