Abstract
There is currently considerable research interest in all-optical signal processing for telecommunication applications. In this paper it is shown that a range of all-optical signal processing functions may be carried out using passive waveguides and phase-shifting elements as basic building blocks. Two types of multimode interference (MMI) photonic circuits, based on silicon-on-insulator (SOI) technology, are discussed in detail. In the first type, phase-shifting elements are added to the ports of MMI couplers. In the second type, the waveguide structure of the MMI coupler itself is modified to achieve a range of signal processing functions. Designs are verified using 2D and 3D simulations.
