    • BODIPY star-shaped molecules as solid state colour converters for visible light communications 

      Vithanage, Chiranthika Dimali Amarasinghe; Manousiadis, Pavlos; Sajjad, Muhammad Tariq; Rajbhandari, Sujan; Chun, Hyunchae; Orofino, Clara; Cortizo-Lacalle, Diego; Kanibolotsky, Alexander; Faulkner, Grahame; Findlay, Neil; O'Brien, Dominic; Skabara, Peter; Samuel, Ifor David William; Turnbull, Graham Alexander (2016-07-06) - Journal article
      In this paper we study a family of solid-state, organic semiconductors for visible light communications. The star-shaped molecules have a boron-dipyrromethene (BODIPY) core with a range of side arm lengths which control ...
    • Fluorescent red-emitting BODIPY oligofluorene star-shaped molecules as a color converter material for visible light communications 

      Sajjad, Muhammad T.; Manousiadis, Pavlos P.; Orofino, Clara; Cortizo-Lacalle, Diego; Kanibolotsky, Alexander L.; Rajbhandari, Sujan; Amarasinghe, Chiranthika Dimali Amarasinghe; Chun, Hyunchae; Faulkner, Grahame; O'Brien, Dominic C.; Skabara, Peter J.; Turnbull, Graham A.; Samuel, Ifor D. W. (2015-04) - Journal article
      Star-shaped organic semiconductors with boron dipyrromethene (BODIPY) cores are color-conversion materials for blue LED-based visible light communications. The difference between 0 and 1 bits is resolved in colour-converted ...
    • MIMO visible light communications using a wide field-of-view fluorescent concentrator 

      Mulyawan, Rahmat; Chun, Hyunchae; Gomez, Ariel; Rajbhandari, Sujan; Faulkner, Grahame; Manousiadis, Pavlos P.; Vithanage, Dimali A.; Turnbull, Graham A.; Samuel, Ifor D W; Collins, Stephen; O'Brien, Dominic (2017-02-01) - Journal article
      This letter reports a demonstration of a 2 x 2 multiple-input multiple-output (MIMO) indoor visible-light communication (VLC) system using a novel fluorescent optical concentrator-based receiver. This potentially allows a ...
    • Ultra-wide coverage VLC system with alignment-free receiver 

      Quintana, Crisanto; Chun, Hyunchae; Mulyawan, Rahmat; Faulkner, Grahame; Collins, Steve; O'Brien, Dominic C.; Xie, Enyuan; McKendry, Jonathan J.D.; Gu, Erdan; Dawson, Martin D.; Manousiadis, Pavlos P.; Vithanage, Dimali A.; Turnbull, Graham A.; Samuel, Ifor D.W. (Institute of Electrical and Electronics Engineers Inc., 2018-03-19) - Conference item
      In this work we present an ultra-wide coverage visible light communication (VLC) system based on a mechanical beam steering system at the transmitter terminal and a fluorescent optical concentrator at the receiver. The ...
    • Visible light communication using a blue GaN mu LED and fluorescent polymer color converter 

      Chun, Hyunchae; Manousiadis, Pavlos; Rajbhandari, Sujan; Vithanage, Dimali A.; Faulkner, Grahame; Tsonev, Dobroslav; McKendry, Jonathan James Donald; Videv, Stefan; Xie, Enyuan; Gu, Erdan; Dawson, Martin D.; Haas, Harald; Turnbull, Graham A.; Samuel, Ifor D. W.; O'Brien, Dominic C. (2014-10-15) - Journal article
      This letter presents a novel technique to achieve high-speed visible light communication (VLC) using white light generated by a blue GaN mu LED and a yellow fluorescent copolymer. We generated white light suitable for room ...
    • Wide field of view fluorescent antenna for visible light communications beyond the étendue limit 

      Manousiadis, Pavlos; Rajbhandari, Sujan; Mulyawan, Rahmat; Vithanage, Chiranthika Dimali Amarasinghe; Chun, Hyunchae; Faulkner, Grahame; O'Brien, Dominic C; Turnbull, Graham Alexander; Collins, Stephen; Samuel, Ifor David William (2016-07-20) - Journal article
      Visible light communications (VLC) is an important emerging field aiming to use optical communications to supplement Wi-Fi. This will greatly increase the available bandwidth so that demands for ever-higher data rates can ...
