Broadly speaking, my current research interests can be divided into two categories: telecommunications and sensing. In terms of telecommunications, I seek to develop solutions that would deliver an improved performance (e.g., bandwidth and infrastructure utilisation, energy efficiency etc.), while reducing the impact of the new technology on the environment. My work in sensing focuses on innovative techniques that can provide enhanced accuracy, efficiency and compactness for environmental monitoring and structural protection. Two aspects of commonality, between these two thematic areas of my research, are optical frequency combs and photonic integrated circuits (PICs). Telecommunications Agile networks: The dominance of telecommunications in every walk of life, the explosion of interest in internet of things (IoT), the relentless requirements for high-speed networking for business, education and leisure, all bring different challenges. My future vision embraces the idea of a service-aware network, with a programmable network substrate performed into existence in response to a service need.At the system level, my research focuses on developing solutions for greener, more efficient optical and converged optical-wireless networks. The main challenge here is to continue to support the rapidly growing volumes of data and at the same time cater for the rapidly increasing dynamicity of the network traffic. This can be achieved by introducing a reconfigurable transport network, to allow for active link capacity optimization, by directing the optimum number of resources, where the demand exists. Such a network would require programmability and reconfigurability in every segment of the physical layer: from the transmitter, through the network nodes to optical receivers. Setting up a viable connection between network nodes will involve planning on the flow level, but also considering the physical aspect of the transmission medium. PIC based OFC: Another spoke of my research, initially supported by the disruptive technology innovation fund (DTIF) project entitled "Irish Lasers for the Internet of the Future (iLife)", is aimed at developing a PIC based expanded optical frequency comb (OFC). It also includes advanced methods of testing and calibrating PIC devices.

• Title

  Irish Lasers for the Internet of the Future - iLife
  Summary

  Optical communication networks are being put under huge strain by the rise in mobile video, video-on-demand, cloud and other bandwidth intensive services. New disruptive innovations are needed to avoid the impending 'capacity crunch' that has the potential to affect the growth of the Internet, with knock-on adverse effects for global economies. Optical Frequency Comb Sources are a new type of laser that enable operators to pack more data into existing fiber infrastructure. The project will develop an photonic integrated optical comb-based transmitter, offering a disruptive value proposition of reduced cost, footprint and power consumption, with simultaneous increase in performance.

• Title

  Comb Based Integrated THz Transmitter - COMBINE
  Summary

  COMBINE aims to design and develop devices enabling photonic-based generation and processing of THz signals. In particular, COMBINE will develop an integrated optical frequency comb-based THz transmitter and investigate the application of a variable pitch grating as an optical switch/tunable optical delay. The THz frequencies have unique properties, useful for applications such as explosives detection, cancer screening, super-high resolution imaging and broadband wireless communications. However, current technologies, operating at such high frequencies are very expensive and inefficient. By employing mature, low loss, commercially available photonics solutions, COMBINE will facilitate the realisation of power and cost efficient THz systems.
