We present the realization of an integrated electrical source of confined surface plasmon polaritons (SPPs) in metal-insulator-metal waveguides. Using an integrated light-emitting diode (LED) and subwavelength slits, we can couple light emitted by the LED directly into waveguided plasmon modes. Polarization-dependent measurements, decay length measurements, and spectral measurements are performed to confirm the electrical excitation of SPPs and characterize the properties of the plasmonic waveguide.
我们展示了在金属-绝缘体-金属波导中实现局域表面等离子体激元（SPP）的集成电光源。通过使用集成发光二极管（LED）和亚波长狭缝，我们可以将 LED 发出的光直接耦合到波导等离子体模式中。我们进行了偏振相关测量、衰减长度测量和光谱测量，以确认 SPP 的电激发并表征等离子体波导的特性。
