HOME > Introduction
Nano-photonics refers to a science that deals with light-matter interaction on a nano-dimensional scale and thus covers a broad range of cross-disciplinary subjects for cutting-edge technologies of photonics. The research group, Nano-Photonics Laboratory (NPL), Department of Physics, Gachon University, which has been led by Professor Heongkyu Ju since 2007, aims to boost synergistic cooperation between various disciplines for the rigorous and original description of physical properties and for its application.
The group research interests include the following but not limited to:
(1) Plasmon-assisted Surface Spectroscopy for Biomedical/Environmental Diagnosis
(2) Plasmon-enhanced Magneto-optical effects
(3) Plasmon-assisted Polymerase Chain Reaction for Biomedical Diagnosis
(4) Interaction of Light with an Active Medium at Optical Resonance
(5) Nonlinear Optical Effects and Its Application
(6) Semiconductor Single Crystal Characterization

The group offers full access permission not only to a variety of electro-optical instruments/optical components but also to facilities/equipments such as a transmission electron microscope (TEM), a nuclear magnetic resonance system (NRM), a XRD system, a scanning electron microscope (SEM), two atomic force microscopes (AFM), a confocal optical microscope, a number of fluorescence microscopes, a fluorescence measurement system, a Fourier transform infrared spectroscope (FTIR), 3D printers, a RF sputter, a number of thermal evaporators, a Raman spectrometer, an UV spectrometer, a furnace, fume hoods (both duct and ductless versions), a cyclic voltametry potentiometer, a semiconductor parameter analyzer, a Hall effect measurement system, a dip coater, a spin coater, an oxygen plasma, a contact angle measurement system, an ultra-cold freezer, a Zeta potential, a number of UV/Vis spectrophotometers, an optical monochromator, and pulsed laser systems (nanosecond and picosecond pulse widths).

We encourage anyone who wishes to enquire of the group researches and the research opportunities for postgraduate programs (Master and Ph.D), to contact the group leader, Professor Heongkyu Ju, department of Physics, Gachon University, Republic of Korea (email: batu@gachon.ac.kr).
