Abstract
Embodiments disclosed herein include an on-cavity photonic integrated circuit (OCPIC). In an embodiment, the OCPIC comprises a laser transmitter, that comprises a row with four bumps, and a micro-ring resonator (MRR) in the row between a first bump and a second bump of the four bumps. In an embodiment, a cavity is below the MRR, where a diameter of the cavity is substantially equal to a spacing between the first bump and the second bump.
