Nonlinear optics in on-chip zero-index metamaterials, at Engineering Physics seminar, Universite de Montreal (Montreal, QC, Canada), Monday, November 23, 2015:
    Optical metamaterials - composite materials whose electromagnetic properties are finely engineered by designing their constituents - have been shown to exhibit strange and exotic properties, such as negligible or negative indices of refraction and the direct control of the amplitude and phase of light. These properties have been used for innumerable applications, such as flat lenses, invisibility cloaks as well as previously unseen nonlinear interactions. Recently, our group has demonstrated the first on-chip metamaterial with a refractive index of zero. These isotropic structures exhibit a...
