文章研究双环掺铒光纤激光器激光混沌偏振产生及其偏振同步思想方法,用偏振器控制产生混沌激光偏振到任意方向,用克尔盒调制控制产生混沌激光旋传偏振态,用四分之一波片进一步控制分解产生新的混沌激光偏振态.调制控制双环掺铒光纤发射系统一路上的克尔盒使输出混沌激光分别产生左旋和右旋圆偏振态,并可动态控制产生混沌圆偏振光;设置接收系统四分之一波片进一步使混沌圆偏振激光控制变化为水平和垂直线偏振态,另一路偏振控制器控制产生水平和垂直偏振光,驱动二个接收子系统且实现和发射系统分别在水平和垂直偏振态上的混沌同步.

In this paper, methods of production polarization and polarization synchronization are presented by using polarization to control chaos in erbium-doped fiber dual-ring lasers. Chaotic lasing can be controlled at an arbitrary vibration direction via controlling a polarizing plate; chaotic circular polarization lights can be produced via modulating a Kerr cell; new directions of vibration of the chaotic lights can be achieved after a quarter-wave plate. Left-handed circular polarization light and right-handed circular polarization light are produced and controlled via controlling and modulating the Kerr cell of the transmitter. Horizontally linear polarized light and vertically linear polarized light can be produced and controlled via the quarter-wave plate in one optical path. In another optical path, horizontally linear polarized light and vertically linear polarized light can be produced and controlled further via the polarizing plates. And horizontally linear polarized light and vertically linear polarized light synchronizations are achieved between the transmitter and two the sub-receivers.
