ULTRAFAST OPTICS (Kim, Dong Eon)
By using femtosecond or attosecond ultrashort pulse, we can measure various kinds of dynamics that take place within the ultrafast time scale femtosecond of attosecond ultrashort pulse that make ultrafast measurement of various kind of ‘fast’ dynamics. Our laboratory develop ultrafast laser source and we research ultrashort time scale phenomina and electron dynamics in atomic, molecule, phase transition, magnetic material and nano structure.
Using SUPERPOSITION and ENTANGLEMENT of quantum mechanics, we can describe it as a quantum superposition state (QUBIT Superposition of 0,1) instead of 0 or 1 which is the basic unit of classical information.
By the this technique we can proceed quantum simulations, quantum computation and quantum cryptography it is possible to enable computational and communication protocols that are not classically possible, our QUANTUM OPTICS & QUANTUM INFORMATION laboratory we research quantum entanglement, quantum imaging and quantum information are being studied using single photons.
Nanostructure-light interaction make quantum and nonlinear physical phenomenon that has not been seen before.
In the QUANTUM NANO-PHOTONICS laboratory, we design and fabricate ultra-small nano-optical devices by the nano fabrication processes to generate quantum photon pairs.
By the using Quantum optical integrated circuits we research quantum cryptography communication. In addition, QUANTUM NANO-PHOTONICS laboratory research various nonlinear phenomena (Brillouin scattering, Raman scattering, OPTOMECHANICS, etc.) occurring in nano-optical devices are under study.
