Im Song Jin, professor, PhD and section chief of the Department of Physics of Kim Il Sung University, has made outstanding achievements in research into nonlinear optics.
He published nearly 40 SCI-class papers including several papers in prestigious academic journals of the world.
Now serving as a reviewer of such organizations as OSA, he published three papers of great significance in the study of nonlinear optics in Physical Review B last year.
His paper “Hysteretic optomagnetic bistability based on the plasmon-induced inverse Faraday effect in magnetoplasmonic disk resonators” dealt with a scientific guarantee for increasing the recording density and speed of information recording devices.
“In developing information recording devices, it is an important matter to increase their recording density and speed. The existing optomagnetic disks ensure high writing speed, but their recording density is low. In this paper we referred to the new discovery of unique magneto-optical recording phenomenon in nanoresonator,” said Im Song Jin.
According to him, the application of the research finding to practice would increase the writing speed and writing density of hard disks thousands of times.
In his other paper published in the same journal “Optically induced nonreciprocity by a plasmonic pump in semiconductor wires”, he suggested a paradigm for optically induced nonreciprocity in semiconductor wires which are spatially asymmetry-free and provide a very simple and efficient platform for plasmonic devices.
In most studies on all-optical diodes, spatial asymmetry has been by necessity applied to break Lorentz reciprocity, Im said.
This principle may open an avenue toward highly integrated all-optical nonreciprocal devices, he added.
