提出并证明了一种新型的电光偏振控制器，它允许在任意两个变化的一般偏振态之间进行无重置的无限偏振变换。这种1.5微米的控制器是用标准的铌酸锂波导实现的，具有数十纳米量级的光学带宽，并且在很大的波长范围内是电子可调的。演示了采用完全模拟电子反馈回路的自动偏振控制。
A novel electro-optic polarisation controller is proposed and demonstrated that allows reset-free endless polarisation transformations between any two varying general polarisation states. The 1.5-mu-m controller is realised with standard lithium niobate waveguides, has an optical bandwidth in the order of tens of nanometres, and is electrically tunable over a wide wavelength range. Automatic polarisation control with an entirely analogue electronic feedback loop is demonstrated.
