activities in FY 2015
March 14, 2016 Joint research on 3D nanofabrication is introduced at the ResOU, Osaka University Homepage as "Hitting the bull's-eye with 3D nanofabrication". Reference: Sekkat, Z. & Kawata, S. Laser nanofabrication in photoresists and azopolymers. Laser & Photonic Reviews 8, 1–26 (2014). Oct 17 - Dec 17, 2015 On behalf of "Japan-Morocco Handai Project on functional nanophotonics", I had the 2-month business trip to MAScIR (Moroccan Foundation for Advanced Science, Innovation and Research) located in Rabat, Morocco. My research task there was to establish high-sensitive pH detector based on SPR (Surface plasmon resonance) sensor. A pH-active molecule used in my laboratory was applied as a sensor layer on thin metal layers designed in MAScIR. Although we are still on the way to conclude about feasibility of pH detection, high sensitivity in SPR sensing with the designed metal layer was indicated by sensing assembly process of the molecules on the metal layers. I'm really glad and excited with this good collaboration between Japan and Morocco, and we will keep on this research with contacting each other. Kentaro Mochizuki (PhD) Kawata laboratory Osaka University February 2016 Ms. Siham REFKI gave a talk "Metal-Insulator-Metal for Plasmonic Sensor" at the meeting of photonics laboratories on 9th Feb., 2015.

April 2014 Our Handai project has been introduced in the Moroccan Journal "Industrie du Maroc" (Industry of Morocco).

May 29th Thursday 13:00-14:00 at Room 213, Photonics Center Seminor Resolution Estimation of Optical Resonance Sensor Structures Speaker: Dmitry Nesterenko, Researcher MAScIR Abstract: Most current theoretical performance analysis of optical resonance sensors (ORSs) is focused on characteristics of resonance response (width of the resonance curve, spectral sensitivity, relation of the spectral sensitivity to the width, relation of height of the resonance dip to the width. However, the aforementioned parameters of the resonance curves have only indirect relation to the resolution of a ORS in common case. We establish a new approach to really estimate the achievable resolution of any types of ORS structures based on the analysis of their resonance response (including Fano type resonance). The figures of merit (FOMs) are introduced for estimation of the resolution for intensity modulation and resonance value modulation with post-processing of bulk media and thin film sensing. The presented approach allows optimization of ORS structures, numerical comparison of their resolution. META14 presentations P17: Resolution estimation of optical resonance sensor structures Dmitry Nesterenko, Sinji Hayashi, Zouheir Sekkat We report on a unified approach for estimating achievable resolution of optical resonance sensor (ORS) structures based on the analysis of their response independently on noise properties of the light source and detector.The figures of merit (FOMs) are introduced for characterization of bulk media and thin film sensing by spectral modulation (SM) and data post-processing, and by intensity modulation (IM). The comparison of the resolution of different types of ORS is performed by numerical simulation. Session 3A17 Bionanoplasmonics II 11:20 : Sharp resonances in waveguide-coupled surface plasmon sensor structures Shinji Hayashi, Dmitry Nesterenko, Zouheir Sekkat We propose a planar structure that allows us to couple a surface plasmon polariton (SPP) mode to a waveguide mode (WGM). Results of reflectivity calculations clearly show very sharp resonances attributed to the Fano resonance and electromagnettically induced transparency (EIT), which may find potential applications in sensing problems.
