   Microcavity Exciton-Polaron-Polaritons in 2D Materials: Physics and Applications

   Presenter: Farhan Rana, Cornell University, United States

    Presentation Details

   Invited

   In doped 2D materials, the two dominant peaks in the optical spectra correspond to superpositions of 2-body-exciton and 4-body-trion states, also called exciton-polarons. The strong coupling of these many-body excitations to photons in microcavities result in exciton-polaron-polaritons whose properties can be controlled via a variety of different techniques. We will discuss the physics and applications of these polaritons.Authors: Farhan Rana, Cornell University / Okan Koksal, NIST Institute for Physical Science and Technology

   Distributed Micron-size III-V Epitaxy on SOI for Integrated Active Devices

   Presenter: Kei May Lau, Hong Kong Univ of Science & Technology, Hong Kong

    Presentation Details

   Invited

   We developed and demonstrated localized III-V epitaxy on SOI platform for photonic integration. Active quantum well laser structures and high-speed photodetectors have been grown laterally from the patterned silicon layer of commercial SOI wafers.Authors: Kei May Lau, Hong Kong Univ of Science & Technology

   Achieving InAs Quantum Dot Laser Operation at and Beyond 150 ^°C

   Presenter: Pawan Mishra, Cardiff University, United Kingdom

    Presentation Details

   We achieved InAs quantum dot-based laser operation up to 170 °C by adopting a codoped active region, including p-modulation doping and direct n-type doping in the InAs quantum dots, without resorting to high-reflectivity facet-coatings.Authors: Pawan Mishra, Cardiff University / Lydia Jarvis, Cardiff University / Chris Hodges, Cardiff University / Sara Gillgrass, Cardiff University / Richard Forrest, Cardiff University / Dagmar Butkovicova, Cardiff University / Craig Allford, Cardiff University / Mingchu Tang, University College London / Huiyun Liu, University College London / Samuel Shutts, Cardiff University / Peter Smowton, Cardiff University

   Narrow linewidth VECSEL for photoionization of Ba for trapped ion computing

   Presenter: Kostiantyn Nechay, Modulight Corporation, Finland

    Presentation Details

   Trapped-ion-based quantum computing is a forerunning approach which ultimately relies on single-frequency lasers. We present narrow linewidth intracavity frequency doubled semiconductor laser platform, here emitting around 553 nm for the efficient Ba atom two-step photoionization.Authors: Kostiantyn Nechay, Modulight Corporation / Luukas Kuusela, Modulight Corporation / Andreas Schramm, Modulight Corporation / Soile Talmila, Modulight Corporation / Pekko Sipilä, Modulight Corporation / Kalle Palomäki, Modulight Corporation / Petteri Uusimaa, Modulight Corporation

   Characterization of Three-Section AlGaInAs Multiple Quantum-Well Mode-locked Lasers for Space Applications

   Presenter: Di Huang, University of Central Florida, CREOL, United States

    Presentation Details

   We report a quantum-well-intermixing-free three-section mode-locked laser diode at 1580nm, featuring 1.70 psec pulse width. The fixed-point frequency analysis shows four different laser parameters conducive for compensating repetition rate and carrier frequency variations in space environment.Authors: Di Huang, University of Central Florida, CREOL
