In this paper, a controllable hybrid plasmonic integrated circuit (CHPIC) composed of hybrid plasmonic waveguide (HPW)-based rhombic nano-antenna, polarization beam splitter, coupler, filter, and sensor has been designed and investigated for the first time. In order to control the power into a corresponding input port, a graphene-based 1 × 3 power splitter with switchable output has been exploited. The functionality of each device has been studied comprehensively based on the finite element method and the advantages over state-of-the-art have been compared. Moreover, the effect of connection of CHPIC to the photonic and plasmonic waveguides has been studied to exhibit the capability of variety excitation methods of the CHPIC. Furthermore, the performance of the proposed CHPIC connected to inter/intra wireless transmission links has been investigated. The wireless transmission link consists of two HPW-based nano-antennas as transmitter and receiver with the maximum gain and directivity of 10 dB and 10.2 dBi, respectively, at 193.5 THz. The suggested CHPIC can be used for applications such as optical wireless communication and inter/intra-chip optical interconnects.
本文首次设计并研究了一种由基于混合等离子体波导（HPW）的菱形纳米天线、偏振分束器、耦合器、滤波器和传感器组成的可控混合等离子体集成电路（CHPIC）。为了控制进入相应输入端口的功率，我们利用基于石墨烯的 1×3 功率分配器实现了可切换输出功能。我们基于有限元法全面研究了每个器件的功能，并比较了其与现有技术的优势。此外，我们还研究了 CHPIC 与光子和等离子体波导的连接，以展示 CHPIC 的各种激励方法的能力。进一步，我们研究了所提出的与内部/外部无线传输链路相连的 CHPIC 的性能。该无线传输链路由两个基于 HPW 的纳米天线作为发射器和接收器组成，其在 193.5THz 处的最大增益和定向度分别为 10dB 和 10.2dBi。该建议的 CHPIC 可用于光无线通信和内部/外部芯片光互连等应用。
