All-Optical Switching and Logic using Microresonators
In this chapter we present the results of all-optical switching and logic experiments carried out in III–V microring resonators. All-optical data processing devices are key components for future integrated photonic circuits. One category of such devices is switching and logic. Architectures have been proposed based on intensity-dependent all-optical logic switches and gates constructed from nonlinear planar waveguide devices such as Mach-Zehnder interferometers and Distributed Bragg gratings [205, 206]. Microring resonators can be used to build elementary switches and logic gates with the added advantages of compact size  and reduced switching threshold [56, 151].
