Abstract :
We present a detailed theoretical analysis of the static and dynamic tuning characteristics of 1.55-μm region three-section tunable DBR lasers under discrete tuning and under continuous tuning. We have analyzed the oscillating wavelength, the Bragg wavelength, and output power characteristics using the rate equation that considers the thermal effect, simultaneously analyzed the heat transfer equation, considering the heat transfer among passive waveguides, the LD chip, the submount, and the heat sink. We experimentally confirm the static and dynamic wavelength tuning characteristics using a highly accurate heterodyne measurement system. Static and dynamic characteristics simulated using the three-section DBR laser model and the thermal model agree with the experimental results presented in this paper
