Ernst 1 ,Bernard Kippelen 1 ; 1 ECE, Georgia Institute ofTechnology, USA. A nonlinear optical (NLO) mirrorstructure can amplify the strong and ultrafastNLO properties of noble metal thin-films. Spectraland angular bandwidths of the NLO mirrors areadjustable while maintaining a large nonlinearreflectance change.CTu3F.7 • 18:15Chirped and Apodized Silicon Gratings EfficientlyCoupled to Normally Incident FiberArray, John L. Covey 1 , Ray T. Chen 1 ; 1 ElectricalEngineering, University of Texas Austin, USA. Asilicon grating coupler containing non-monotonicchirp, apodization, and quasi-periodicity is fabricated,re-designed, and measured. Simultaneousinput/output coupling from a standard fiber arrayat normal incidence results in a 60% coupling efficiencyper grating.CTu3G.8 • 18:15RF Photonic Filters with 20-ns BandwidthReconfiguration Based on Optical FrequencyCombs, Rui Wu 1 , Daniel E. Leaird 1 , AndrewM. Weiner 1 ; 1 School of Electrical and ComputerEngineering, Purdue University, USA. We presentbandwidth reconfigurable RF photonic filteringwith 20-ns reconfiguration speed based on afrequency comb with rapidly switched opticalbandwidth.CTu3H.7 • 18:15Rapid, wide bandwidth pulsed cavity ringdownspectroscopy, Toby K. Boyson 1 , Dylan R. Rittman 2 ,Thomas G. Spence 3 , Maria E. Calzada 3 , Abhijit G.Kallapur 1 , Ian R. Petersen 1 , Paul Kirkbride 4 , DavidS. Moore 2 , Charles C. Harb 1 ; 1 School of Engineeringand Information Technology, UNSW, Australia;2Shock and Detonation Physics Group, Los AlamosNational Laboratory, USA; 3 Department of MathematicalSciences and Department of Chemistry,Loyola University New Orleans, USA; 4 Forensicand Data Centres, The Australian Federal Police,Australia. We present a new variant of the CavityRingdown Spectroscopy (CRDS) that is able toscan across more than 1400 nm of spectral bandwidth,acquiring and analysing more than 150,000spectral datapoints in less than four seconds.18:30–20:30 Conference Reception and JTu4A • POSTER SESSION I: Nanophotonics, Lightwave Communications and Biophotonics,Exhibit HallNOTES__________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Tuesday, 11 JuneConcurrent sessions are grouped across four pages.
