研究目的
To propose and study a new type of all-optical logic gates utilizing SEM GSPPs with compressed sizes, due to its strong field confinement property.
研究成果
The study demonstrates the promising potential of SEM GSPPs to act as optical functional devices, with XOR and XNOR gates designed to validate the proposed concept.
研究不足
The coherence length of the carrier in graphene nanoribbon is expected to be only a few nanometers at room temperature, which is much smaller to the sizes of the graphene nanoribbons and the SPPs wavelength, and may have little effect to the propagation of SPPs in graphene nanoribbons here.
