摘要	An optical device comprises a fiber having a cladding and a core, and a target PIC waveguide having a cladding and a core. The cladding on one side of the input fiber is removed at the end of the fiber and a flat surface is created along the fiber core, close to the core, exposing the fiber core. A flat-bottomed channel optionally having an in-plane angle with respect to the symmetric axis of the PIC waveguide is fabricated on the top layer of the PIC waveguide in the coupling area, exposing the upper surface of the optionally tapered planar waveguide. The flat surface of the fiber and the top surface of the waveguide is contacting, so the core of the fiber is intersected at an angle with respect to the symmetric axis of the target waveguide and close together at the intersection as an interacting region to define a hybrid waveguide.
其他摘要	一种光学器件，包括具有包层和纤芯的光纤，以及具有包层和纤芯的目标PIC波导。输入光纤一侧的包层在光纤末端被除去，并且沿着光纤芯产生平坦表面，靠近芯，暴露光纤芯。在耦合区域中的PIC波导的顶层上制造可选地具有相对于PIC波导的对称轴的面内角度的平底通道，从而暴露可选锥形平面波导的上表面。光纤的平坦表面和波导的顶表面是接触的，因此光纤的纤芯相对于目标波导的对称轴以一定角度相交，并且在交叉处靠近在一起作为相互作用区域以限定混合波导。
