초록

본 논문에서 수행된 DFB(distributed feedback)-LD(laser diode)의 DC와 AC 특성 분석을 위한 모델링은 레이저 다이오드 공진기 내의 spatial hole burning과 $\lambda$/4 위상천이 된 회절 격자의 영향을 고려한 것으로서 DC특성 분석을 위한 시뮬레이션을 통하여 공진기내의 광파워 분포와 캐리어 밀도 분포 그리고 광-전류 곡선등을 얻었으며, AC 특성 분석을 위한 시뮬레이션으로부터는 비교적 정확한 IM 응답과 FM의 위상과 크기 응답을 얻었다.

In this paper, modeling for DC and AC characteristics analysis of DFB-LD was performed considering effects of .lambda./4-shifted gratingandspatial hole burning within a laser diode cavity. From the simulation for DC characteristics, Light-Current curve, optical power distribution and carrier density distribution within the cavity can be obtained. The simulation for AC characteristics porovides IM response and the amplitude and phase and the amplitude and phase response of FM with excellent accuracy.
