Michelle R Stem
Complete Consulting Services, USA
Keynote: Quantum laser interactions with select silicate specimens
Time : 09:00-09:30
Biography:
Michelle R Stem has a PhD in Materials Science Engineering, MBA in Management and BS in Chemistry. She has done Post-doc Research and continued work as Senior Materials Researcher at Complete Consulting Services, LLC. She applies interdisciplinary expertise through multi-scale analysis, computational modeling and laboratory synthesis to study extremely rare inorganic, complex and semi-conductor (ICS) materials. She researches ICS structural and property variations to discover and ultimately engineer new methods, applications, models, materials and metamaterials with the goal of controlling photonic, phononic, optoelectronic, band gap and other properties. In addition, her research develops materials that save energy (e.g. power differentials for photonic band gap versus electronic materials) and finds alternatives to using up rare resources.
Abstract:
This presentation will show never-before-seen colorful micrographic images of select natural silicate specimens interacting with various laser sources. These micrographs will reveal a closely magnified view of materials with rare properties, such as anti-Stokes upconversions and negative index metamaterials. In contrast to currently available manufactured materials, the natural materials to be presented display these rare properties under conditions in which the currently available manufactured materials cannot function, e.g. ambient temperatures, ambient pressures, no radioactive elements, no heavy metals, no added photons, no electricity and ambient air environment. A goal is to develop materials with the photonic control displayed by these natural materials for applications that include: solar power, space exploration, energy efficiency, stealth technologies, photonic waveguides and data storage/transmission.

Abstract:
Multi-pixel imaging devices such as CCD, CMOS and FPA photo-sensors dominate the imaging world. These photodetector array (PDA) devices certainly have their merits including increasingly high pixel counts and shrinking pixel sizes, nevertheless, they are also being hampered by limitations in instantaneous linear dynamic range, inter-pixel cross-talk, quantum full well capacity, signal-to-noise ratio, sensitivity, spectral flexibility and in some cases, imager response time. Recently invented is the coded access optical sensor (CAOS) smart camera that works in unison with current PDA technology to counter fundamental limitations of PDA-based imagers while providing extreme linear dynamic range, extreme image security, extreme inter-pixel isolation and high enough imaging spatial resolution and pixel counts to match application needs. This talk describes the basics of the CAOS smart camera invention using the Texas instruments (TI) digital micromirror device (DMD). The talk highlights recent experimental demonstrations of both white light and multi-spectral CAOS-based imaging including CAOS-mode imaging over a 136 dB linear dynamic range. Novel applications of the CAOS smart camera include automotive and surveillance imaging where smartness to identify vital targets in extreme contrast scenarios is vital for both mobile and stationary system operations.

Keynote: Antimicrobial blue light inactivation of pathogenic microbes: State of the art
Time : 08:30-09:00
Biography:
Tianhong Dai is working as an Assistant Professor of Harvard Medical School. His research interest is centered around light-based antimicrobial therapy. In particular, his laboratory has been interested for some time in using antimicrobial blue light to treat multidrug-resistant localized infections. He is the author or co-author of over 80 peer-reviewed publications and has been the PI of NIH R01, NIH R21, DoD, CIMIT as well as grants from other funding sources. He is the Founding Chair of the conference “Photonic Diagnosis and Treatment of Infections and Infl ammatory Diseases (Conference BO113)” at the SPIE Photonics West, BIOS.
Abstract:
As an innovative non-antibiotic approach, antimicrobial blue light in the spectrum of 400-470 nm has demonstrated its intrinsic antimicrobial properties resulting from the presence of endogenous photosensitizing chromophores in pathogenic microbes and subsequently, its promise as a counteracter of antibiotic resistance. Since we published our last review of antimicrobial blue light in 2012, there have been a substantial number of new studies reported in this area. Here we provide an updated overview of the fi ndings from the new studies over the past fi ve years, including the effi cacy of antimicrobial blue light inactivation of diff erent microbes, its mechanism of action, synergism of antimicrobial blue light with other antimicrobials, its eff ect on host cells and tissues, the potential development of resistance to antimicrobial blue light by microbes and a novel interstitial delivery approach of antimicrobial blue light. Th e potential new applications of antimicrobial blue light will also be discussed.

Yongsoo Lee
Oh and Lee Medical Robot, Inc, South Korea
Keynote: Combination laser treatment for immature scars
Time : 09:00-09:30
Biography:
Yongsoo Lee completed his Medical degree at Yonsei University, South Korea. He is the Co-Founder and Co-CEO of Oh and Lee Medical Robot, Inc. and affi liated to Yonsei YL Laser Dermatology and Plastic Surgery in South Korea. He has published many papers in respected journals and has served as an Editorial Board Member of medical journals. He also served as the sole Editor of “Scars and Scarring: Causes, Types and Treatment Options,” published by Nova Biomedical, New York, USA.
Abstract:
Surgical scar revision (SSR) has been the main treatment modality for scars, with few alternative options until lasers were developed and were found to be useful. Combination laser treatment (CLT) and combined CLT and SSR have not been studied in detail, despite evidence demonstrating that the combination of these modalities could result in statistically better outcomes. Immature scars (IS), a novel class of scars, defi ned as “scars whose features are not yet expressed,” are situated at a treatment nexus between SSR and CLT. Vascular lasers have been shown to improve scar quality with treatment on the suture removal day, while fractional lasers are being tested on scars in early stages. However, there are few studies on early laser treatment of scars and no guidelines for the treatment of IS. Th e recently published article by the author demonstrates how IS need to be treated for better outcomes. Th e study also provides useful guidelines for practitioners, based on statistical analysis. Th e study design and statistical methodology of the study will be presented orally and the results are summarised as follows. Th e outcome of facial scarring is more enhanced than that observed in non-facial scars. Facial scars in patients under the age of 15 exhibited greater results when compared to facial scars in older patients. Th e choice of initial vascular laser used on facial scars, either 532nm or 585nm, had no signifi cant eff ect on scar outcome. Th erefore, it is advised that CLT be initiated as soon as possible aft er stitch removal to improve facial scar outcome. Furthermore, younger patients are expected to have a more improved result than those who are older.

Amr S Helmy
Univeristy of Toronto, Canada
Keynote: Integrated hybrid plasmonic devices–the role of 2D materials
Time : 09:30-10:00
Biography:
Amr S Helmy is a Professor at the Department of Electrical and Computer Engineering and the Director for the Center of Quantum Information and Quantum Control at the University of Toronto. Prior to his academic career, he held a position at Agilent Technologies, R&D division, in the UK between 2000 and 2004. At Agilent his responsibilities included developing InP-based photonic semiconductor integrated circuits and high-power lasers. He received his PhD and MSc from the University of Glasgow with a focus on photonic devices and fabrication technologies, in 1999 and 1995 respectively.
Abstract:
Hybrid plasmonic devices and the associated circuits, with applications in data communications will be discussed. In addition, the role of 2D materials in this platform will be highlighted. Recent advances in the development of a range of 2D materials brings signifi cant opportunities and challenges to photonic circuits. Because of their thicknesses, when compared to optical wavelengths in the visible and infrared, 2D materials physically overlap with a small fraction of the guided electromagnetic modes at these wavelengths in an integrated setting. In this talk, a new approach to profi t from 2D materials in integrated planar setting through the utilization of hybrid plasmonic structures and anisotropic meta-materials will be discussed. Due to the dissipative nature of plasmonic modes there is an inherent trade-off between the propagation losses and modal confi nement in their implementation. Th is talk will also demonstrate an eff ective approach that utilizes hybrid plasmonic modes to alleviate the trade-off associated with their loss behavior and the modal confi nement factor. Th is new approach holds promise to provide eff ective, nano-scale photonic devices using 2D materials, with losses approaching those exhibited by their dielectric counterparts such as Si. Example devices that profi t from this novel architecture include optical modulators, cavities and detectors with designs specially tailored to eff ectively utilize 2D materials. Th e performance metrics and fi gures of merit of this new class of integrated photonic devices will also be described in the talk and compared with other technologies to demonstrate their superiority.
