设计了一种采用沟槽结构的混合等离子体波导器件。这种波导器件的设计目的是通过将等离子体器件与传统的波导结构连接起来，来提高等离子体器件与光学电路的亲和力。该波导器由三个结构段组成，包括两个用于输入和传输的传统波导段和一个混合等离子体波导管。利用时域有限差分法等数值分析技术对所设计的波导结构进行了评估。器件的传输特性影响着导光与表面等离子体激元之间的干涉。通过控制由涂有金层的传统波导组成的混合波导器件的长度，可以控制器件的传输强度。该器件的传输特性可以根据入射光的波长与混合波导器件的长度之间的关系来控制。该装置将只传输特定波长的入射光，因为混合等离子体波导的长度保持不变。该器件的特性表明了其在纳米器件、光学集成电路和等离子体传感器方面的应用潜力。
A hybrid plasmonic waveguide device was designed using a trench structure. This waveguide device was designed to improve the affinity of plasmonic devices with optical circuits by connecting them with traditional waveguide structures. The waveguide device consists of three structural segments, comprising two traditional waveguide sections for input and transmission and a hybrid plasmonic waveguide. The designed waveguide structure was evaluated using numerical analysis techniques such as the finite-difference time-domain method. The device's transmission property affects the interference between the guided light and the surface plasmon polaritons. Controlling the length of the hybrid waveguide device, which is composed of a traditional waveguide coated with a gold layer, allows the transmission intensity of the device to be controlled. The device's transmission characteristic can be controlled based on the relationship between the wavelength of the incident light and the length of the hybrid waveguide device. The device will transmit only specific incident light wavelengths because the length of the hybrid plasmonic waveguide remains constant. The characteristics of this device indicate potential for applications to nanoscale devices, optical integrated circuits and plasmonic sensors.
