   Demonstration of an Air-Water Communication Link Through Dynamic Aerosol and Water Curvature When Considering the 2-D Modal Coupling of a Spatially Structured Beam

   Presenter: Haoqian Song, University of Southern California

    Presentation Details

   We experimentally investigate the 2-D modal power coupling of LG11 and HG11 beams under dynamic aerosol and water curvature, and demonstrate a 1-Gbit/s LG11 FSO link, having a penalty of ~3-dB compared with no-effect cases.Authors: Haoqian Song, University of Southern California / Runzhou Zhang, University of Southern California / Huibin Zhou, University of Southern California / Kaiheng Zou, University of Southern California / Nanzhe Hu, University of Southern California / Xinzhou Su, University of Southern California / Hao Song, University of Southern California / Kai Pang, University of Southern California / Yuxiang Duan, University of Southern California / Daeyoung Park, Inha University / Brittany Lynn, Naval Information Warfare Center Pacific / Greg Gbur, University of North Carolina at Charlotte / Aristide Dogariu, University of Central Florida / Richard Watkins, Clemson University / Jerome Miller, Clemson University / Eric Johnson, Clemson University / Moshe Tur, Tel Aviv University / Alan Willner, University of Southern California

   Free-Space Optics for Communications at Sea

   Presenter: Katherine Newell, Johns Hopkins University Applied Physics Laboratory

    Presentation Details

   Invited

   We discuss our free-space-optical communication system, specifically exploring tradeoffs in pointing, acquisition, and tracking design and the use of retransmission to mitigate the impact of turbulence-induced fades.Authors: Katherine Newell, Johns Hopkins University Applied Physics Laboratory / Michelle O'Toole, Johns Hopkins University Applied Physics Laboratory / Krunal Patel, Johns Hopkins University Applied Physics Laboratory / Raef Youssef, Johns Hopkins University Applied Physics Laboratory / Radha Venkat, Johns Hopkins University Applied Physics Laboratory / Adam Willitsford, Johns Hopkins University Applied Physics Laboratory / Noah Talisa, Johns Hopkins University Applied Physics Laboratory

   Momentum Space Controlled Flexible Spatial Light Modulator for Optical Wireless Communication

   Presenter: Zizheng Cao, Technische Universiteit Eindhoven

    Presentation Details

   Invited

   Traditional spatial light modulators (SLMs) shape an incident wavefront pixel-by-pixel. This talk explores a new class of SLMs named momentum space controlled spatial light modulators (MSC-SLMs). An optical-wireless-communication link enabled by MSC-SLMs is demonstrated.Authors: Zizheng Cao, Technische Universiteit Eindhoven / Xinda Yan, Technische Universiteit Eindhoven / Yiwen Zhang, university of southern california / Chao Li, Peng Cheng Laboratory / Juhao Li, Peking University / Chia Wei Hsu, university of southern california / Ton Koonen, Technische Universiteit Eindhoven

   Core Selective Switch Supporting 15 Cores per Port Using Bundled Three 5-Core Fibers

   Presenter: Yudai Uchida, Kagawa University

    Presentation Details

   We prototyped a 15-core 1×8 core selective switch (CSS). The high core count CSS is achieved by bundling three 5-core fibers (5-CFs) and collimating/demultiplexing beams from the input bundled three 5-CFs using a single microlens.Authors: Yudai Uchida, Kagawa University / Tsubasa Ishikawa, Kagawa University / Itsuki Urashima, Kagawa University / Shoma Murao, Kagawa University / Takahiro Kodama, Kagawa University / Yasuki Sakurai, Santec Corporation / Ryuichi Sugizaki, Furukawa Electric Co., Ltd. / Masahiko Jinno, Kagawa University

   A CMOS Compatible on-Chip MMI Based Wavelength Diplexer With 60 Gbit/s System Demonstration

   Presenter: Zakriya Mohammed, New York University- Tandon School of Engineering

    Presentation Details

   An ultra-compact (41µm) 1310/1550 nm diplexer with an insertion loss < 1 dB and extinction ratio > 20 dB for both the wavelengths is demonstrated. Furthermore, experiments show clear eye diagrams at 60 Gbit/s signals.Authors: Zakriya Mohammed, New York University- Tandon School of Engineering / Bruna Paredes, New York University Abu Dhabi / Mahmoud Rasras, New York University Abu Dhabi

   Silica-PLC Based Mode-Dependent-Loss Equalizer for Two LP Mode Transmission

   Presenter: Takeshi Fujisawa, Hokkaido University

    Presentation Details

   A mode-dependent-loss (MDL) equalizer based on silica-PLC is proposed for three-mode transmission and experimentally demonstrated for the first time. By selectively attenuating LP01-mode, 1.5-dB MDL equalization is demonstrated for the setup with large LP11-mode loss.Authors: Takeshi Fujisawa, Hokkaido University / Takayoshi Mori, NTT / Junji Sakamoto, NTT / Yoko Yamashita, NTT / Taiji Sakamoto, NTT / Ryota Imada, NTT / Ryoto Ima, Hokkaido University / Takanori Sato, Hokkaido University / Kei Watanabe, NTT / Ryoichi Kasahara, NTT / Toshikazu Hashimoto, NTT / Kazuhide Nakajima, NTT / Kunimasa Saitoh, Hokkaido University

   64-QAM Self-Coherent Transmission Using Symmetric Silicon Photonic Stokes-Vector Receiver

   Presenter: Shota Ishimura, The University of Tokyo

    Presentation Details

   We propose a robust silicon photonic Stokes-vector receiver based on fully symmetric waveguides without a mode-selective directional coupler. By using a fabricated receiver, we experimentally demonstrate 30-Gb/s 64-QAM self-coherent transmission over a 25-km single-mode fiber.Authors: Shota Ishimura, The University of Tokyo / Taichiro Fukui, The University of Tokyo / Ryota Tanomura, The University of Tokyo / Go Soma, The University of Tokyo / Yoshiaki Nakano, The University of Tokyo / Takuo Tanemura, The University of Tokyo
