A new integrated optical component is introduced that performs the function of the well-known microwave magic T, i.e., that produces the sum and the difference of the two input optical signals. Two structures are proposed and tested theoretically for this purpose. The first is based on the symmetric Y junction, and the second is based on interference phenomena in a multimode waveguide. The theoretical design is tested with a beam-propagation method simulation, and good performance is obtained. The effects of the geometrical design parameters on the structures’ performance (bandwidth, cross talk, and losses) are also investigated.
