Scientist Sheds Light on Nonlinear Optical Effects of Nanoparticles

Among the top scientists and technicians of the DPRK in 2020 announced this year is Prof. Im Song Jin (pictured), PhD at the Physics Department of Kim Il Sung University.

The 43-year-old elucidated the nonlinear optical effects of nanoparticles in the plasmon resonance, thereby greatly contributing to the country’s advanced basic science studies and the development of the world’s physics.

Born into an ordinary office employee’s family, he dreamed of becoming a brilliant scientist.

He began to have such a dream when he was attending Pyongyang Middle School No. 1. In his final year at the school he won the top prize at the national programming contest.

Afterwards, he consolidated his theoretical foundation at the physics faculty, graduate school and natural science research institute. In those years, he presented a doctoral thesis to obtain a doctorate in physics at the age of 29. He majored in nonlinear nano-optics.

As a branch of advanced basic science based on the interaction of light and materials in the nano sphere, nonlinear nano-optics is the focus of world academic attention since it provides the theoretical and methodological bases of a new generation of information, nano, energy and materials technologies.

Having begun with photon crystal fibre, he and his research group have expanded the scope of nonlinear optical study to solar cell, plasmon, graphen device and metal nano composite complex to achieve successes.

Among them, the research into nonlinear optical phenomena in nano plasmon resonance is attracting worldwide attention

He completed a new simulation method capable of getting up-to-date test results with no high-performance calculating facility.

The research group led by him verified magnetic mechanism based on light and presented a new method of realizing the magnetic record in nano size at ultrahigh speed before elucidating the principle of interaction between external magnetic fields and plasmon resonances in the structure of magnetic plasmon.

As he designed a new model of optical modulator, a core element of future information technology, he was awarded twice the February 16 Science and Technology Prize, the top sci-tech honour in the DPRK.

He was registered as one of the best scholar in the Who’s Who after presenting dozens of essays to the world’s influential journals and he is now on the screening committee of several foreign sci-tech journals.

After introducing many subjects and training two PhDs in their 20s, he is now exerting himself to train talents.
