영문 초록

In this paper, we performed the modeling of a tunable three section DFB-LD with continuous phase using the coupled-wave equation. It was also proposed new modeling method for λ/4 phase shifted one. We got the characteristics of oscillation wavelength, gain, and photon density profiles according to parameters such as coupling coefficient K and current into the third sections for two case of continuous phase and λ/4 shifted phase one. The simulations for λ/4 phase shifted tunable three section DFB-LD prove that the continuous tuning range is about 4.2nm for K=120㎝?, L=180㎛, and the oscillation mode be within the stop-bands. Also when changed a current of both end sections, it is shown that a photon density reaches the maximum at the center.
