光子学提供了一个关键的解决方案，以限制现有硅技术带来的无数挑战。在这里，我们提出了一个简单的2通道等离子体解复用器与金属-绝缘体-金属（MIM）波导的几何形状。解复用器能够分离两个基本光学窗口（即，1310 nm和1550 nm）。采用时域有限差分法（FDTD）对该结构进行了数值模拟.还研究了该解复用器的光学特性。建议的解复用器的性能测量使用串扰和品质因数。串扰的最小值为− 30 dB，最大品质因数为60。由于金属损耗大，最大透射率限制在45%。所提出的解复用器是超紧凑的尺寸，并能够提供亚波长限制。它适用于WDM应用，并为光子集成电路的设计提供了一条途径。
Photonics provides a key solution to limit the myriads of challenges offered by existing silicon technology. Here, we propose a simple 2-channel Plasmonic demultiplexer with Metal-Insulator-Metal (MIM) waveguide geometry. The demultiplexer is capable to separate two fundamental optical windows (i.e., 1310 nm and 1550 nm). An FDTD (finite difference time domain) method is used to investigate the structure numerically. The optical properties of the demultiplexer are also investigated. The performance of the proposed demultiplexer is measured using crosstalk and quality factor. The minimum value of crosstalk is − 30 dB and maximum quality factor is 60. The maximum transmission is limited to 45% due to large metallic losses. The proposed demultiplexer is ultra-compact in size and is capable to provide sub-wavelength confinement. It is suited for WDM applications and can pave a way to design the photonic integrated circuits.
