Unlocking the Potential of Photonic Crystals: Exploring Designs for High-Performance Switches

Electronic device speed and energy consumption restrictions have motivated the scientific community to seek alternatives to these limitations. All-optical digital circuits and systems are a natural alternative to this problem. The devices based on photonic crystals through various published works have revealed their great potential for this type of application due to the high speeds with low energy consumption reached. The combination of switches N and P allows the construction of several logic gates and combinational circuits. However, switches must produce more robust results that may require daisy chaining multiple devices together. This work evaluates the impact of changes in the design and operation of switches N and P through changes in the interference system, pulse duration, and analysis of the effects of various types of curvatures in the proposed systems. The presented results show that some changes can increase the performance of switches and allow the construction of more complex devices more efficiently.
