Abstract:
1. A method comprising: receiving, from a first package of a package-on-package stack and by a first optical interface of the package-on-package stack, an optical signal; wherein the optical interface is located on an upper surface of a second package of the package-on-package stack; transmitting, by the optical interface of the package-on-package stack, the optical signal to the second package; wherein the first optical interface comprises routing paths for routing optical signals between the first package and the second package; selecting, by the first optical interface, a routing path from the routing paths; wherein the optical signal is transmitted to the second package using the selected routing path; receiving, by the second package of the package-on-package stack, the optical signal transmitted by the first optical interface; wherein the optical signal received by the first optical interface comprises data from a first component associated with the first package; and transmitting the optical signal that is received by the second package and comprises the data to a second component associated with the second package.
