Abstract: An optical cavity structure for bending optical signals is provided. The optical cavity structure includes an input port for receiving input optical signals from a first waveguide. The optical cavity structure also includes an interconnecting structure that receives said input optical signals and interconnects said first waveguide to a second waveguide, the interconnecting structure further includes at least four straight edges that orthogonal and of a finite width. The optical cavity structure further includes an output port coupled to the interconnecting structure for providing the second waveguide with the input optical signals. Further, the optical cavity structure may be used to create three dimensional splitter devices and resonators.

Abstract: A method and apparatus for splitting/coupling optical signal(s). A unitary waveguide section having a first lateral dimension perpendicular to a propagation axis of the unitary section is provided. An offset waveguide section is optically coupled to the unitary waveguide section. The offset waveguide section has a second lateral dimension approximately equal to twice the first lateral dimension. Two branching waveguide sections having first ends are optically coupled to the offset section at the first ends.

Abstract: A 3D coupling system includes a layered structure that receives an input of a defined mode size. The layered structure includes a plurality of layers with varying indexes, and outputs a vertically mode converted beam associated with the input beam. A planar lens structure receives the vertically mode converted beam, and performs lateral mode conversion on the vertically mode converted beam. The 3D coupling structure outputs a laterally and vertically mode converted beam. A high index-contrast waveguide structure receives the laterally and vertically mode converted beam, and provides the laterally and vertically mode converted beam to a receiving device with less than 1 dB loss.
