Multi-mode interference device |
| 摘要 |
A multi-mode interference (MMI) device includes a substrate layer, a core layer grown on the substrate layer for propagating an optical signal, and a cladding layer grown on the core layer for guiding the optical signal. The MMI device includes a patch with a non-uniform shape formed by an intersection of a plurality of curves forming a non-uniform refractive index distribution within the MMI device. The plurality of curves includes at least one curve with a non-null curvature. |

1. A multi-mode interference (MMI) device, comprising:
a substrate layer; a core layer arranged on the substrate layer for propagating an optical signal; and a cladding layer arranged on the core layer for guiding the optical signal, wherein the MMI device includes a patch with a non-uniform shape formed by an intersection of a plurality of curves forming a non-uniform refractive index distribution within the MMI device, wherein the plurality of curves includes at least one curve with a non-null curvature, and wherein the plurality of curves includes at least one spline. |
