Photonic wafer scale interposer with angled beam grating couplers

An apparatus for sending data comprising:

• a photonic wafer-scale interposer (PWSI), wherein the PWSI includes a plurality of waveguides;
• a plurality of chiplets, wherein the plurality of chiplets is bonded to a front side of the PWSI, wherein the plurality of chiplets includes at least one surface-emitting light source, a first chiplet, and a second chiplet;
• an optical element (OE), wherein the OE angles light, from a first surface-emitting light source within the at least one surface-emitting light sources;
• and
• a grating coupler within the PWSI, wherein the grating coupler couples light that was angled from the first surface-emitting light source, to a first waveguide within the plurality of waveguides.

A system for sending data comprising:

• a photonic wafer-scale interposer (PWSI);
• a plurality of chiplets;
• an optical element (OE);
• and
• a grating coupler within the PWSI, wherein the system is configured to:
• use the PWSI, wherein a front side of the PWSI is bonded to the plurality of chiplets, wherein the plurality of chiplets includes at least one surface-emitting light source, a first chiplet, and a second chiplet, and wherein the PWSI includes a plurality of waveguides;
• send data, by the first chiplet, to a first surface-emitting light source within the at least one surface-emitting light source;
• emit light, by the first surface-emitting light source, wherein the light that was emitted is based on the data that was sent, and wherein emitting includes angling the light, by the OE;
• couple, by the grating coupler within the PWSI, the light that was angled from the first surface-emitting light source, to a first waveguide within the plurality of waveguides;
• and
• receive, by the second chiplet, the data that was sent, wherein the receiving is based on the light that was coupled to the first waveguide.
