Optics and Photonics Elite Research Center


The OPERA center covers all aspects of scientific, engineering and technological studies on the materials, devices, modules, and systems to achieve integrated VLSI photonics and opto-electronics as applicable to electronics, telecommunications, computers, avionics, transportation systems, bio-medical systems, and environmental industries.


In the first three-year stage, the center will develop a new device to be called the optical printed circuit board (O-PCB), which is intended to complement or supersede electrical printed circuit board (E-PCB). In the second three-year stage, we will develop technologies for VLSI integration of micron-scale photonic and opto-electronic devices and modules based on O-PCB technology. In the third three-year stage, we will develop technologies for VLSI integration of nano/quantum-scale photonic and opto-electronic devices and modules.

Human Resource Training

The OPERA center has established itself as a global leader in the field of photonic integrated technology and provides a training and educational platform for graduate students, post-doctorate researchers , professors, researchers, and other industrial participants and associates. In the SPIE academic society, the director of the OPERA center co-chairs an international conference every year on this subject and provides world-wide leadership. Also, in October every year, the center holds an international symposium, where world class leaders and distinguished scholars are invited to give lectures on their recent advances in this and related technologies. Domestically, every Saturday, the OPERA center holds a seminar program, where all the participants give talks on the recent development of their research and findings for education and further research. The OPERA center also collaborates with the Optical Technology Education Center at Inha University and provides educational programs periodically on optical integration technology to the professionals working in this area. The center is frequently invited to the world-class academic conferences and workshops to give invited and plenary talks for world-wide training and education.
