Enhanced Heating Efficiency in Graphene-Based Electrodes: A Comparative Analysis

This research presents a comparative analysis of the heating efficiency of graphene-based electrodes in contrast to traditional metal heating electrodes. The proposed structure demonstrates an improved heating efficiency stemming from the integration of graphene, which eliminates the requirement for an intermediate SiO2 isolation layer. This structural modification results in reduced losses and mitigates mode field mismatch, leading to enhanced heating performance. However, the optical bandwidth of the device is constrained by the resonance effect, and further efforts are necessary to diminish the insertion loss.
