环形光纤激光器中的半导体光波导调制器

Optical Modulators Using Semicondutor Waveguide in Fiber Ring Lasers

对环形光纤激光器中的半导体光波导调制器进行了理论研究，结果表明，光纤环中的偏振控制器对光的偏振态的控制以及半导体光波导对光的偏振态的调节构成了激光器的主要调制机理，为环形光纤激光器的自调Ｑ及锁模的新机制提供了理论依据。

Optical modulators using semiconductor waveguide in fiber ring lasers are investigated theoretically. The analysis shows that the modulation mechanism resulted from the polarization control in the fiber loop and polarization adjustment of semiconductor waveguide. This provides a theoretical evidence for a new type of selfstaring modelocked and selfQswitched meachanism in fiber lasers.
