Abstract:
A low loss high extinction ratio on-chip polarizer. The polarizer includes an input waveguide taper having an outer waveguiding region that widens in the direction of light propagation along at least a portion of the taper length, and a core waveguiding region that narrows in the direction of light propagation along at least a portion of the taper length, so as to selectively squeeze out light of undesired modes into the outer regions while preserving light of a desired mode in the waveguide core. An output filter section is provided to prevent light from reentering the output waveguide after being squeezed out. An integrated light absorber/deflector may be coupled to the outer waveguiding regions.

Claim (Index 4):
The waveguide polarizer according to  claim 2 , wherein the output filter section comprises a pair of angled surfaces, each at an acute angle to the output waveguide on opposite sides thereof, both facing substantially rearwardly towards the mode separating section for reflecting light in the slab waveguiding region away from the output waveguide on opposite sides thereof.
