The wave mode calculation of a large-scale optical system in comparison to the working wavelength is practically impossible because the computational cost increases exponentially. In this paper, we propose a method that can obtain the optical mode in a large-scale optical system. The method carries out simulations by dividing the calculation area into blocks and moving along the light axis along which the light propagates. By applying this method to the calculation of resonant modes in a ring-type optical resonator, which is mainly used for ring laser optical gyro sensors, the efficiency of the proposed method was verified.

In this paper we demonstrate how to use optical simulation to enhance OLED performance. Using stateof-the-art p-i-n OLEDs, we validate our optical model by fitting key figures like current, power, and quantum efficiencies to the experimental results. We finally provide general design guidelines for optically optimized OLEDs.

This paper considers a network restoration algorithm for all-optical WDM networks. As the increasing traffic and transmission speed, any failure on the networks will lead to loss of huge data and disruption of the services. Therefore, a network restoration algorithm is necessary for the high-speed all-optical networks. This paper suggests a distributed restoration algorithm for line or channel level failures under the dynamic rerouting. For the algorithm, some measures for performance evaluation are explicitly derived and simulation studies are exploited to evaluate its usability by SLAM(Simulation Language for Alternative Modeling) II.

The As2S3 thin film has a characteristics of optical modulation in both amplitude and phase. Since the As2S3 thin film can be used as a real-time reconfigurable optical filter, the fSDF filter can be optically fabricated on it. According to the modulation characteristics of the As2S3, the optimal fSDF filter recorded on this thin plate has the form of continuous amplitude and binary phase. Computer simulation and optical experiments on the optical pattern classification show that the As2S3 is suitable for the optical fSDF filter.

본 논문에서는 직경 $125{\mu}m$의 싱글모드 광섬유에 입사된 빔을 다방향으로 방사하기 위하여 이론적으로 계산된 값을 광학설계 프로그램인 LightTools를 이용하여 광섬유 끝단에 원뿔형 구조물을 모델링 하고 입사된 모든 빔이 전반사 되어 측면으로 방사되는 광섬유 팁과, 전방과 측면으로 동시에 방사가 가능한 광섬유 팁에 대해 시뮬레이션을 하였다. 이러한 결과를 가지고 광섬유 끝단에 펨토초 레이저와 $CO_2$ 레이저를 이용하여 원뿔형 구조물을 제작하고 시뮬레이션 결과와 비교 분석하는 연구를 수행하였다.
