Abstract
A waveguide having a gradient-index (GRIN) waveguide lateral coupler is provided. In an example embodiment, the waveguide comprises an active region. The refractive index profile of the active region is non-constant.
Claims20
A waveguide formed on a substrate, the substrate defining a plane, the waveguide comprising:
- an active region, wherein a refractive index profile of the active region is non-constant in a first direction parallel to the plane defined by the substrate.
A photonic integrated circuit comprising:
- a waveguide formed on a substrate, the substrate defining a plane, the waveguide comprising:
- an active region, wherein a refractive index profile of the active region is non-constant in a first direction parallel to the plane defined by the substrate.
