Theory and design of periodic couplers.
The theory of periodic couplers is examined from the point of view of the reciprocity theorem and a modified Born scattering approach. Design equations for several coupler configurations are presented. Efficiency and aperture size calculations are compared with previously published data for grating and Bragg couplers.
