We demonstrategiant and broadband enhancement of the nanocrystalabsorption cross section in close packednanocrystal superlattices, which is the first reporton a collective optical phenomenon in this type ofself-assembled metamaterials to date.QTu1B.7 • 12:45Tunable, Epitaxial, Semimetallic Films and forPlasmonics, Erica Krivoy 1 , Alok Vasudev 2 , HariP. Nair 1 , Vaishno D. Dasika 1 , Ron Synowicki 3 , RodolfoSalas 1 , Scott J. Maddox 1 , Mark Brongersma 2 ,Seth Bank 1 ; 1 Microelectronics Research Center, TheUniversity of Texas at Austin, USA; 2 Departmentof Materials Science and Engineering, StanfordUniversity, USA; 3 J.A. Woollam Co., Inc, USA. Wepresent rare-earth monopnictide alloys as tunableMid-infrared epitaxial semimetals for plasmonics.The La(1-x)Lu(x)As system combines high carrierconcentrations, epitaxial compatibility with manyIII-V substrates, and tunable plasma reflectionedge throughout much of the Mid-infrared.QTu1C.8 • 12:45Hyperentanglement in Semiconductor Waveguides,Dongpeng Kang 1 , Lukas G. Helt 2 , SergeiV. Zhukovsky 2,1 , Juan P. Torres 3,4 , John E. Sipe 2 , A.S. Helmy 1 ; 1 Electrical and Computer Engineering,University of Toronto, Canada; 2 Physics, Universityof Toronto, Canada; 3 ICFO-Institut de CienciesFotoniques, Spain; 4 Departament of Signal Theoryand Communications, Universitat Politecnica deCatalunya, Spain. A proposal to generate modaland polarization hyperentangled photons usingBragg reflection waveguides is discussed. Ahigh quality of entanglement is achievable withspectral filtering using filter bandwidths of a fewnanometers.QTu1D.8 • 12:45Linewidth Anisotropy of the Heavy Hole Excitonin (110)-Oriented GaAs Quantum Wells, RohanSingh 1,2 , Travis M. Autry 1,2 , Gaël Nardin 1 , GalanMoody 1,2 , Hebin Li 1 , Klaus Pierz 3 , Mark Bieler 3 ,Steven T. Cundiff 1,2 ; 1 JILA, University of Colorado &NIST, USA; 2 Physics, University of Colorado, USA;3Physikalisch-Technische Bundesanstalt, Germany.We report crystal-axis dependent homogeneouslinewidths of the heavy hole exciton resonance ina (110)-oriented GaAs quantum well measured usingtwo-dimensional Fourier transform spectroscopy.The increase in homogeneous linewidth withtemperature shows an activation-like behavior.13:00–14:00 Lunch and Unopposed Exhibit Only Time, Exhibit Halls 1 and 2 (concessions available)14:00–16:00 Market Focus Session II: Photonics Entrepreneurs, Exhibit Hall 2Tuesday, 11 JuneNOTES___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________100CLEO: 2013 • 9–14 June 20132013CLEO Tuesday.indd 95/17/13 3:10 PM
