Abstract
A low loss high extinction ratio on-chip polarizer has at bi-layer optical taper with an input port of width Wthat communicates with a mode squeezer, followed by an S-bend (or dump bend), and finally a taper having an output port of width W. The illumination that passes through the low loss high extinction ratio on-chip polarizer has a TMmode converted to a TEmode which is lost in the mode squeezer and S-bend section, while an input TEmode is delivered at the output as a substantially pure TEsignal of nearly undiminished intensity.
