System and method for optical input/output arrays |
摘要 |
System and method embodiments are provided for high density on-chip optical input/output (I/O) arrays with partition waveguide routing topology. System and apparatus embodiments for on-chip optical I/O arrays provide for doubling the density of optical I/O arrays in a given footprint on a photonic integrated circuit (PIC) chip. System and apparatus embodiments for on-chip optical I/O arrays also provide waveguide routing topology to provide signal feedback to facility automated active alignment and coupling of optical fiber arrays in to surface grating coupler elements without use of waveguide crossings and without intersecting with waveguides connecting devices to I/O ports. In an embodiment, a PIC chip includes a plurality of first optical I/O elements and a plurality of second optical I/O elements, wherein a row of I/O elements comprises alternating ones of the first optical I/O elements and the second optical I/O elements. |

1. A photonic integrated circuit (PIC) chip, comprising:
a plurality of first optical input/output (I/O) elements; and a plurality of second optical I/O elements, wherein a row of I/O elements comprises alternating ones of the first optical I/O elements and the second optical I/O elements, wherein the PIC chip is configured such that first optical elements couple to the first optical I/O elements from a first side of the PIC chip and second optical elements couple to the second optical I/O elements from a second side of the PIC chip; and a waveguide routing topology that provides signal feedback to facilitate automated active alignment and coupling of an optical fiber array into surface grating coupler (SGC) elements. |
