Paper Abstract

The cavity theory model was proposed to discuss the wavelength tuning. The coupling efficiency between semiconductor gain chip and FBG has great influence on the output characteristics. The mode coupling theory and ZEMAX numerical simulation software are used to get the coupling efficiency curves, which are changed with alignment errors. The results show that the conical lensed fiber’s coupling efficiency is highest, and adjustment tolerance is largest. We also completed the experiment of center wavelength tuning and beam quality.
