Abstract
An optical waveguide polarizer having a transverse electric wave pass mode. The waveguide polarizer includes an upper cladding layer, a core layer, and a lower cladding layer arranged in a vertically stacked relationship. The core layer includes an electro-optic polymer. The waveguide polarizer has a plurality of electrodes disposed on the upper and lower cladding layers and along both sides of a longitudinal region in the core layer such that the plurality of electrodes form electric fields in a direction substantially perpendicular to the core layer and along both sides of the longitudinal region so that a transverse electric wave mode is guided through the longitudinal region and a transverse magnetic wave mode is substantially extinguished in the longitudinal region.
