    • 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.
    • 本发明提供了一种具有多模干涉耦合器的光学装置,其被配置为将条形波导光学耦合到时隙光子晶体波导。 多模干扰耦合器对槽隙光子晶体波导具有大于或等于90%的耦合效率,大约等于槽光子晶体波导的缺陷宽度的宽度,等于或小于1.5μm的长度 并且在给出约为零的终止参数的周期的边缘处与时隙光子晶体波导接口。 光学装置还可以包括设置在多模干涉耦合器和狭缝光子晶体波导之间的绝缘间隙,其中多模干涉耦合器的长度减小绝缘间隙的宽度的大约一半。
