The distinctive switching property between crystalline and amorphous states of a Phase-Change Material (PCM) made it very attractive choice for agile, programmable Photonic devices. This speech will report some selective results from the GST and GSST-based photonic switches and metasurface designs which are programmable and agile.
B. M. Azizur Rahman received the B.Sc.Eng and M.Sc.Eng. degrees in Electrical Engineering with distinctions from Bangladesh University of Engineering and Technology (BUET), Dhaka, Bangladesh, in 1976 and 1979, respectively. He also received two gold medals for being the best undergraduate and graduate students of the university in 1976 and 1979, respectively. In 1979, he was awarded with a Commonwealth Scholarship to study for a PhD degree in the UK and subsequently in 1982 received his PhD degree in Electronics from University College London. In 1988, he joined City, University of London, as a lecturer, and became a full Professor in June 2000. At City University, he leads a large research group on Photonics Modelling, specialised in the use of rigorous and full-vectorial numerical approaches to design, analyse and optimise a wide range of photonic devices. He has published more than 650 journal and conference papers, and his journal papers have been cited more than 9200 times and h-index of 43. He has supervised 34 students to complete their PhD degrees as their first supervisor and received more than £13 M in research grants. Prof. Rahman is Life Fellow of the IEEE, and Fellow of the Optical Society of America and the SPIE.
