Abstract:
The present invention provides an optical apparatus having a multimode interference coupler configured to optically couple a strip waveguide to a slot photonic crystal waveguide. The multimode interference coupler has a coupling efficiency to the slot photonic crystal waveguide greater than or equal to 90%, a width that is approximately equal to a defect width of the slot photonic crystal waveguide, a length that is equal to or less than 1.5 μm, and interfaces with the slot photonic crystal waveguide at an edge of a period that gives a termination parameter of approximately zero. The optical apparatus may also include an insulation gap disposed between the multimode interference coupler and the slot photonic crystal waveguide, wherein the length of the multimode interference coupler is reduced by approximately one half of a width of the insulation gap.
