Riza completed his Cambridge University (U.K.) 1978 O-level and 1980 A-level overseas school certificates with Double Distinction in Mathematics. In August 1981, Riza joined the Illinois Institute of Technology in , graduating in August 1984 with a B. S. degree in Electrical Engineering (EE). He graduated amongst the top 3 seniors of the entire institute, receiving the Illinois Institute's Highest Academic Honor, the IIT Alumni Association Academic Achievement Award. Riza joined the California Institute of Technology (Caltech) in on a full graduate scholarship in October 1984. He received his M.S. degree in EE in June 1985, and completed his doctorate in the same field in Oct., 1989. In 1988, Riza's graduate work on antenna controls won him an International Society for Optical Engineering (SPIE) Student Scholarship Award. A decade later in 1998, The International Optical Society (OSA) honored Riza with a Fellow Award for his pioneering work in photonic controls for radars and antenna arrays. After completing his Ph.D. work in 1989, Riza joined the Liquid Crystal Display (LCD) Group at the General Electric Corporate Research and Development (GE-CRD) Center, New York. Upon joining GE-CRD, Riza showed how LCD technology could be used for optically controlling antenna arrays. For his High Risk/High Impact research ideas for GE-Aerospace, he received a 1990 GE-CRD New Start Research Award. The next 5 years, Riza led the GE Optically Controlled Radar Project. At GE, he continued his research in acousto-optics and also initiated the earliest works in simple electronic control liquid crystal lenses. In 1998, SPIE presented him with a Fellow Award for his research contributions in acousto-optic signal processing and liquid crystal devices. With the sale of GE Aerospace to Lockheed-Martin in 1995, Riza decided to join academia at a new Optics Center
called CREOL as an Associate Professor, being promoted to Full Professor in 2001. Prof. Riza
established CREOL's first Photonic Information Processing Systems Laboratory that focused on research in Applied Optics with pioneering works in power plant sensors,biomedical optics, nano-scale test & measurement optical instruments, fiber-optic communications, acousto-optic signal processing, optical MEMS, liquid crystal devices, microwave photonics and radar, and freespace laser communications. These works are described in over 336 publications (145 Journal papers) and 44 issued patents. In 2000, Riza launched a startup Company, Nuonics, Inc., to commercialize inventions. Riza is the Editor of the reference book on Photonics and Antenna Controls. For his pioneering works in photonic signal processing and fiber-optics, Riza received the International Commission for Optics 2001 ICO Prize and 2001 Ernst Abbe Medal from Carl Zeiss Foundation-Germany. In 2007, Riza received an IEEE Fellow Award for his pioneering contributions to the international field of Applied Optics. In 2007, Riza was Visiting Professor at the Delft University of Technology. In 2008, Riza was one of three scientists awarded the Eramus-Mundus Scholar Award by the European Union (EU) Erasmus Masters Optics Program. Riza was one of eight worldwide individuals/project groups in applied laser technology and commercialization to receive the German 2008 Berhold Leibinger Innovation Prize Nominee Distinction Award for his invention of hybrid laser beam profiler technology. Riza received a 2009 and 2010 IEEE Photonics Society Distinguished Lecturer Award for his work in extreme optical sensors and a 2009 Science Foundation Ireland Walton Award as Distinguished Visiting Fellow at National Univ. of Ireland-Galway. In August 2011, Riza was appointed Chair Professor of EEE and Department Head, University College Cork, Ireland and Associate Member, Tyndall National Institute, Ireland. In 2011, he received the IET (former IEE) Fellow Award and in 2012 he received the European Optical Society (EOS) Fellow Award. In 2011, Riza established the first IEEE Student Section at UCC. Riza authored his first textbook Photonic Signals and Systems: An Introduction, in January 2013, published by McGraw Hill. In June 2013, Prof. Riza was appointed as the Head (Dean) of the School of Engineering at UCC.

Photonic Information Processing Systems Laboratory

“Creating a Knowledge Base for Research and Teaching”

Riza Photonics group’s research and teaching activities use the physics of optics and the information manipulations of mathematics to invent, design, build and test innovative devices, sub-systems, and systems to solve current problems in science and engineering and to provide new approaches to study scientific fields. By nature, these efforts are multidisciplinary, requiring knowledge at both the optical device level and the system application level. In a sense, one plays with LEGO® style optical and electronic building blocks to realize inventions. So far, Riza group innovations have come in the following research areas.

-- Aerospace/Defense

Riza’s Defense Optics activities started from his Caltech Ph.D days in the mid-80’s where he showed for the first time how acousto-optics could be used to control transmit and receive mode phased array radars. Later work revolved around developing next generation highest phase stability acousto-optic signal processors such as convolvers, correlators, and spectrum analyzers for wideband Electronic Warfare (EW) applications. Additional innovations included powerful Range-Doppler and transversal filter optical implementations suited for extreme bandwidth and signal complexity radar signal processing. Another aspect of Riza group innovations includes a series of novel beamforming control systems for Phased Array Radars for both narrowband and wideband operations. The group has also pioneered optical security systems using multi-dimensional optical ID cards and a new Hybrid Photonic Signal Processing technique that combines the worlds of analog and digital signal processing..

-- Biomedicine/Health

Riza’s interest in medical optics goes back to his 1989 General Electric (GE) days with the development of simplest control liquid crystal electronic lens motivated by vision applications. Between 1995-1998, Riza’s group introduced the use of optics for phased array ultrasound controls including the concept of intracavity optical wavelength to one dimensional space mapping using an intracavity single fiber probe and spatial distribution via wavelength multiplexing. Since 1998, the group has also proposed and demonstrated several novel optical imaging systems such as the first acousto-optic design based Optical Coherence Tomography (OCT) system, Angstrom sensitivity high speed scanning interferometric imagers, fiber-based scanning imaging endoscopes, and confocal microscopes such as spectral microscopes and agile no-moving parts microscopes.

-- Communications

Riza and co-workers contributions in the field of communication have ranged from both the optical fiber domain to the laser communications wireless arena. In the fiber-optic signal attenuation arena, the group has pioneered the most diverse set of variable optical attenuator (VOA) modules using optical MEMS, acousto-optic, and liquid crystal (LC) technologies. The group for example proposed and demonstrated the world’s first fault-tolerant variable attenuators, all-digital fiber-optic switches, and wavelength sensitive add-drop filters. Riza also invented the Hybrid MEMS/LC design for fiber-optic applications including the hybrid analog-digital design for producing world record performance VOAs. In the free-space wireless domain, Riza invented Multiplexed Optical Scanner Technology, a new method for no-moving parts three dimensional steering of light beams. The group also developed the most advanced theoretical models for freespace-to-Single Mode Fiber (SMF) lens coupling that has realized amazing near zero loss SMF-to-SMF optical power transfer for short distances and expected low loss designs for long range optical wireless links.

-- Energy/Measurement Instrumentation

Generation and control of clean energy is an important research area for any society. Riza and co-workers are developing novel extreme environment optical sensors needed for Zero Emissions fossil fuel-based power generation systems. In addition, Riza and coworkers have developed a new class of laser beam profilers such as the world’s first all-digital and hybrid optical beam profiler instruments using MEMS and new minimally invasive and all-digital profilers using Liquid Crystal technology. These designs have been used for imaging using both coherent and incoherent light. New tools for optical surface metrology have also been invented and demonstrated using acousto-optics and liquid crystals that enable nano-scale measurements.
