Liam Barry

Principal Investigator

Liam Barry received his BE (Electronic Engineering) and MEngSc (Optical Communications) degrees from University College Dublin in 1991 and 1993 respectively. From 1992 until 1996 he was employed as a Research Engineer in the Optical Systems Department of France Telecom’s Research Laboratories. During this period his research involved the use of ultra-short optical pulses in high capacity optical networks, and as a result of this work he obtained his PhD Degree from the University of Rennes. In February 1996 he joined the Applied Optics Centre in Auckland University, New Zealand, as a Research Fellow and in 1998 he took up a lecturing position in the School of Electronic Engineering at Dublin City University (DCU), and established the Radio & Optical Communications Laboratory. He is currently a Full Professor in DCU and his main research interests are; all-optical signal processing, hybrid radio/fibre communication systems and tuneable lasers for reconfigurable optical networks.

He has published over 500 articles in internationally peer reviewed journals and conferences, holds 9 patents in the area of optoelectronics, has co-founded two companies in the photonics sector, and has supervised 36 research graduate students to completion (29 at PhD level). He was a TPC member for the European Conference on Optical Communications (ECOC) from 2004 to 2016 and served as conference co-chair for ECOC in Dublin in 2019. He also served as a TPC member and Chair of the Optoelectronic Device Strand for the Optical Fibre Communication Conference. He is currently an Associate Editor for IEEE Photonics Journal and IEEE/OSA Journal of Optical Communications & Networks.

The Radio and Optical Communications Group was established in 1999 as part of the HEA Programme for Research in Third Level Institutions (PRTLI). The focus of the laboratory is to develop innovative devices, systems and technologies for future broadband communication and sensing systems. The Laboratory has the ability to accurately characterize novel high speed devices, and sub-systems including:

  • Initial simulation/modeling of the optical and optoelectronic devices
  • Complete systems simulations to demonstrate device performance
  • Detailed characterization of optical and optoelectronic devices
  • Performance testing of novel devices & sub-systems in coherent & direct detection testbed (56Gbaud PAM4, 33Gbaud 64QAM, 100G OFDM, etc.)

Some of the key research programmes in the laboratory are as follows:

  • Applications of tuneable laser diode in optical networks
  • Generation, characterisation & optimisation of optical frequency combs for spectrally efficient systems
  • Development of all-optical processing technologies for Tb/s systems
  • Design of hybrid radio/fibre systems for broadband access and 5G networks
  • Design, realization & characterization of new lasers for THz emission and sensing applications
  • Characterizations of novel single mode lasers for access networks
  • Implementation of novel modulation formats for optical systems
