Co-packaged Optics

Co-packaged optics (CPO) are heterogeneous integration packaging methods to integrate the optical engine (OE) which consists of photonic ICs (PIC) and the electrical engine (EE) which consists of the electronic ICs (EIC) as well as the switch ASIC (application specific IC). The advantages of CPO are: (a) to reduce the length of the electrical interface between the OE/EE (or PIC/EIC) and the ASIC, (b) to reduce the energy required to drive the signal, and (c) to cut the latency which leads to better electrical performance.
