SUMMARY:Complex Nano Photonics: from Physics to Device Engineering
DESCRIPTION:Featuring Luca Dal Negro\, Boston University\nHosted by: Shyams
	under Erramilli\nPoster: http://physics.bu.edu/internal//files/download/Luc
	a-poster.pdf\n\nPart of the Physics Department Colloquia Series.\n\nThe abi
	lity to manipulate light-matter interactions using multiscale\, aperiodic e
	lectromagnetic media is at the heart of current nanoplasmonics and metamate
	rials technologies. Besides its fundamental interest\, photonic-plasmonic c
	oupling in complex aperiodic environments is also of great importance for a
	 number of engineering device applications such as broadband nano-antennas\
	, super-resolution focusing structures\, complex laser nano-cavities\, and 
	optical biochemical sensors.  In this talk\, I will discuss selected aspect
	s of our work on the design and engineering of field localization and reson
	ant scattering phenomena in aperiodic metal-dielectric nanostructures with 
	enhanced optical cross sections for light emission\, energy conversion\, op
	tical sensing\, and infrared detection. I will also survey recent progress 
	towards 3D light localization in photonic devices\, control of critical fra
	ctal resonances and compact localization (CL) including the engineering of 
	Bound States in the Continuum (BIC) of open-scattering aperiodic media. In 
	addition\, I will address novel opportunities offered by the methods of fra
	ctional calculus and fractional transport equations in aperiodic photonics 
	along with their relevance to the engineering of more efficient laser devic
	es with reduced threshold operating in the anomalous diffusion regime. The 
	novel concept of a "fractional random laser" will be introduced along with 
	detailed predictions on its laser threshold and dynamical behavior. Finally
	\, I will present our activities on the development of novel low-loss diele
	ctrics with tunable negative permittivity from the visible to the infrared 
	spectral range\, opening new vistas towards largely scalable\, multi-band p
	lasmonic nanostructures and photonic metamaterials entirely compatible with
	 the widespread Si technology.  \n \nReferences:  \n \n1) R. Wang\, F. A. P
