Abstract
According to this disclosure, embodiments of the present invention include photonic integrated circuits having active and passive geometric regions geometrically arranged to provide for more compact integrated photonic integrated circuits which, in turn, leads to higher chip yields and lower fabrication costs.
Claims19
A photonic integrated circuit, comprising:
- a substrate having a surface and a plurality of edges, the surface having a first area defined by the plurality of edges of the substrate;
- and
- a plurality of signal channels provided on the substrate, each of the plurality of signal channels comprising a plurality of optical elements, a first one of the plurality of signal channels defining a first boundary of a second area in the surface of the substrate, and a second one of the plurality of signal channels defining a second boundary of the second area, remaining ones of the plurality of signal channels are positioned between the first and second ones of the plurality of signal channels, such that the remaining ones of the plurality of signal channels are provided on the second area,
- wherein a ratio of the second area to the first area is greater than or equal to about 0.5.
