The ICO/ICTP Award Committee members, Mourad Zghal (Chair and ICO VP), Ahmadou Wagué (ICO VP), Joseph Niemela (ICO VP), Anna Consortini (ICO former President) and Mitcho Danailov, awarded the 2016 ICO/ICTP Gallieno Denardo Award to two researchers: Jehan Akbar of Pakistan and Mati Horprathum of Thailand.

Dr Jehan Akbar obtained his MSc In physics at the University of Peshawar, Pakistan, in 2007, and his PhD at the University of Glasgow, UK, in 2012 under the supervision of Dr Anthony E Kelly and Professor Catrina Coleman. He is currently an Assistant Professor of Physics at Hazara University Mansehra, KPK, Pakistan, and an ICTP Junior Associate. His research work is mainly related to development of semiconductor optical amplifiers and high-power mode-locked lasers.

Dr Akbar was awarded for “his breakthrough contributions in the design and fabrication of high performance semiconductor lasers and amplifiers as well as for promotion of research activities in optics and photonics in Pakistan”. Dr Akbar designed and fabricated a 40 GHz semiconductor mode-locked laser monolithically integrated with distributed Bragg reflector (DBR) and semiconductor optical amplifier (SOA), producing an average output power of 200 mW and peak power of 1.15 W (Photonics Technology Letters, Vol 25, Issue 3, 2013).

He also designed and fabricated a novel monolithic device for adjustable gain clamping in SOAs. The device consists of two tunable distributed Bragg gratings and a gain section and enables the gain of the SOA to be regulated. The gain could be controlled by adjusting the wavelength overlap of two Distributed Bragg Reflector gratings positioned at either side of the active region (Journal of Light Wave Technology, Volume 31, No 16, 2013).

Dr Akbar has recently developed Erbium doped and Ytterbium doped fibre mode-locked lasers for femtosecond pulses generation. Both these oscillators were mode-locked by nonlinear polarization rotation. The Er doped fibre modelocked lasers were developed to be used for pump source for titanium sapphire laser crystal, which is used as seed laser for free electron laser.

He has received several national and international awards for his research contributions. Dr Akbar presented his research work in various leading international conferences held in Turkey, Italy, the UK, Japan, South Africa and the USA. His diverse research activities have led to high-impact publications and to new research directions followed by many other researchers. He has published 40 research papers in various international journals and conferences.

His statement: “This unexpected recognition of my efforts gives me a sense of hope and big confidence. I will redouble my efforts in future for promotion of research activities and optics in Pakistan. I will enjoy doing so as I find great satisfaction in doing research and promoting science.”

Dr Mati Horprathum, a researcher with the National Electronics and Computer Technology Center, Thailand, was awarded for “his valuable contributions in the development of optical thin-film technology for innovative surface functionality as well as for his commitment in the diffusion of optical thin-film research in Thailand”.

Mati Horprathum received his B Ed in science– physics in 2003 from Srinakarinwirot University and his MS and PhD in physics from King Mongkut’s University of Technology Thonburi, Thailand in 2006 and 2009, respectively. Since 2006, he started his career with National Electronics and Computer Technology Center (NECTEC), Thailand. From 2006 to 2011, he worked with Photonic Technology Laboratory and was responsible for research in optical thin-film coatings, characterizations, vacuum coating systems based on physical vapour deposition, and co-ordination with other research groups in Thailand. In 2011, he received a postdoctoral fellowship supported by Japan National Project “the Funding Program for Next Generation Word-Leading Researcher”. During the postdoctoral position, he worked at Laboratory of Atomic Scale Materials Processing, Institute of Scientific and Industrial Research (ISIR), Osaka University, Japan in the “Green Innovation Science” project, and was responsible for developments of growth and alignment of uniform oxide nanowires and developments of nanostructures by top-down and bottom-up techniques. Since 2013, he has been a researcher at Optical Thin-Film Laboratory, NECTEC, Thailand. His current works involve thin-film and nanostructure areas, i.e., glancing-angle deposition, nano-microelectronics mechanic devices, surface-enhanced Raman spectroscopy (SERS), fabrications and characterizations of nanostructures, optoelectronic devices, electrochromic thin films, spectroscopic ellipsometry, vacuum designs, and thin-film characterizations. Through his career, his major interests are to utilize the optical thin-film and nanostructure technologies towards local industrial manufactures, as well as medical and environmental applications in Thailand. He also enjoys giving lectures in the optical thin-film and nanotechnology to undergraduate and graduate students, and engineers working on optical industries in Thailand. He has authored and co-author more than 50 refereed journals, 100 proceedings, and has been a regular reviewer for 10 journals. He also holds two Thai patents, and nine Thai patent applications. In addition, he has also organized five international conferences and events in surface sciences, thin-film coatings, and sensors.
