Photonics beyond diffraction limit： Plasmon waveguide, cavities and integrated laser circuits
报告摘要：
I will discuss recent development in scaling down of photonics. First I will present theoretical and experimental investigation of passive low loss waveguide using hybrid plasmon design. We propose a new optical cavity design approach using indefinite medium that has a drastically different scaling law than conventional microcavities, and discuss its experimental demonstrations. Finally we will show an active plasmonic laser circuit that integrated with 5 tiny cavities that multiplexed into a single waveguide-an effort towards integrated photonics at nano-scale.
