Physics and Astronomy Colloquium
Structured matter for exotic light control
Presented by Stavroula Foteinopoulou, ECE Dept., Univ. of New Mexico
Light is ubiquitous in modern technologies. This stresses the need to tailor the behavior of light beyond what natural materials offer. Judicious sculpturing of matter can unleash a range of exotic light phenomena by exploiting a carefully balanced synergy between optical responses of materials and their geometry. The characteristic size scale of these "meta-structures," which can range from much smaller to similar to the wavelength of the impinging light, is critical in determining the system's photonic response. Here I discuss my work with a variety of metaphotonic systems that can demonstrate an effective negative refractive index, artificial magnetism, slow light, non-resonant electric field enhancement and confinement, as well as perfect absorption with perfect reflectors. These extra-ordinary capabilities can find applications in microscopy, imaging, sensing, detection, non-classical light sources and all-optical circuitry.
