Strong Coupling and Coherent Phenomena in Semiconductor Metamaterials

  • Author / Creator

  • Metamaterials are nanoengineered materials with electromagnetic properties beyond those found in nature. Recently, interest has focused towards controlling light matter interaction using metamaterials for applications in nanoscale emitters from lasers to single photon sources. We propose an active metamaterial with embedded quantum wells that strongly interact with unique electromagnetic modes of the nanostructured medium. This strong interaction is characterized by the phenomenon of strong coupling wherein the modes of a metamaterial show energy splitting at the intersubband transition wavelength of the embedded quantum wells. Additionally, we show that semiconductor metamaterials can mediate superradiant behaviour between a pair of emitters across distances greater than their radiation wavelength. This work paves the way for realizing quantum strong coupling and coherent effects in semiconductor metamaterial structures.
