Method and apparatus for enhancing the extinction ratio in mode converters

A method and apparatus for optimizing a non-ideal, real mode converter to substantially achieve the performance of an ideal mode converter. The method consists of optimizing the input linear polarization to the mode converter to balance the power in the principal modes of the mode converter at the o...

description A method and apparatus for optimizing a non-ideal, real mode converter to substantially achieve the performance of an ideal mode converter. The method consists of optimizing the input linear polarization to the mode converter to balance the power in the principal modes of the mode converter at the output of the mode converter. This has the effect of maximizing the orthogonality of the output polarization states of the mode converter. The present invention also provides an electro-optical mode converter with means to adjust the orientation of the input polarization state to substantially balance the power in the principal modes at the output of the converter. In the case of an intensity modulator, the output polarization state can also be adjusted to maximize mode conversion and extinction ratio.
