Abstract
A method of using a passive polarization sorter comprising the step of deploying a first waveguide and a second waveguide forming an adiabatic region along a portion of their length. Then, an input optical signal is introduced into the first waveguide wherein light having at least one guided TE polarized mode of mode ranking mode-i-TE and at least one guided TM polarized mode of mode ranking mode-j-TM remaining within the first waveguide. Light having the other one of the TE and TM polarized modes is evanescently coupled into the second waveguide in the adiabatic region.
