Dr Mike Parker has over 25 years experience in photonics and wireless technologies. During his career, he has pioneered many important technologies, including his doctoral research (at Cambridge University, 1993-1996) where he invented the use of liquid crystal on silicon (LCoS) technologies for high-resolution holographic flexgrid (WDM) wavelength control for optical telecommunications.
Having received his PhD, Dr Parker worked for over 10 years at Fujitsu (1997-2007), located in the UK, USA, and Japan. While with Fujitsu he invented the use of cascaded and cyclic arrayed-waveguide gratings (AWGs) in an optical access network topology, now forming the dominant physical-layer architecture for next-generation passive optical networking (PON) high-speed broadband networks. In 1998 he invented the application of aperiodic grating structures to photonic crystals, creating the only means to achieve a multi-wavelength photonic bandgap, forming the basis for the world’s first electronically-tunable THz quantum cascade laser (QCL). In recent years, he has also pioneered the application of thermodynamic principles to computation and communications theory, advocating the first absolute energy efficiency metric (dBe) for ICT technologies. He has also invented novel microstructured optical fibre using Fresnel zones, azimuthally graded-index (GRIN) fibre, and pioneered the use of optical orbital angular moment (OAM) light for cryptographic telecommunications.
From 2007-2018 Mike was a Research Fellow working with Prof. Stuart Walker at University of Essex where he innovated in the application of entropy theory to the design of flexgrid elastic optical networking, researching closely with BT. He is now currently a Visiting Fellow at Essex University. Mike has also researched 5G technologies (optical and wireless) in various EU H2020 and 5G-PPP research projects, where he used millimetre-wave (mmW) technologies for high capacity, massive IoT, and high performance 5G telecommunications systems.
A surprising consequence emerging from his research collaboration with BT is that Mike was able to develop with Prof. Chris Jeynes (Surrey University) a new geometric entropy theory based on the Principle of Least Exertion (a path-integral based variational calculus) and Maximum Entropy. They have applied their new theory to the structure of DNA as well as double-armed spiral galaxies, such as the Milky Way, to provide an alternative physical understanding to the issue of the so-called “dark matter”.
Mike is the Founder and CEO of his own technology consultancy company, Lexden Technologies Ltd., where is currently involved in the EU 5G-PPP Phase-2 project 5G Metro-Haul. He has filed over 20 patents, and published 177 conference & journal papers over his career.
