Aims and Scope

The origin of New Physics: Sae Mulli (NPSM, ISO abbreviation: New Phys.: Sae Mulli.): Sae Mulli (새물리 in Korean characters means ‘new physics’) is the oldest Korean pure scientific journal. It was first published in 1961 just after the Korean War by the Korean Physical Society (KPS). The primary mission of Sae Mulli was to start building up Korean physics research community from almost nothing and in fact Sae Mulli had made tremendous contributions to the Korean science community. Through a peer-review system, Sae Mulli had continued elevating the level of scientific researches, consequently becoming a cornerstone of the economic miracle of Korea...

We have designed and fabricated a planar lightwave circuit (PLC) Michelson interferometer device with a long delay path length for quantum cryptography. Faraday rotator mirrors were employed to improve the birefringence polarization effect in the asymmetric planar lightwave circuit, and a phase-modulated quantum cryptography system was constructed on the basis of the time-division interference scheme. The path difference in the present Michelson interferometer is 40.6 cm within a 0.2 mm error, and the excess loss is 1.56 dB. A quantum error rate of 2% was obtained from the quantum cryptography system utilizing the present asymmetric planar lightwave circuit interferometer.

Effects of Nanogaps on the Whispering Gallery Modes in a Microring Resonator

In this work, we designed a two-dimensional (2D) microring resonator (Q ~ 8 $\times$10$^5$) and numerically studied the effects of a nanogap on the whispering gallery modes (WGMs). For this purpose, the finite element method with COMSOL multiphysics software was employed. Perturbations of the WGM resonances, which depend on the size and the angle of the nanogap, can be characterized by using the shift, Q value, and splitting of the resonance peaks. For studying the size dependence, we varied the thickness of the horizontal gap from 0 to 140 nm. The resonance wavelengths were increasingly blue-shifted with increasing thickness. The angle dependence showed that the whispering gallery modes were perturbed more strongly by an oblique gap than by either a horizontal or a vertical gap. These results indicate that oblique defects inside a resonator have more critical effects on a high-Q microring resonator than horizontal or vertical ones.
