An interconnect package integrates a photonic die, an electronic die, and a switch ASIC into one package. At least some of the components in the electronic die, such as, for example, the serializer/deserializer circuits, transceivers, clocking circuitry, and/or control circuitry are integrated into the switch ASIC to produce an integrated switch ASIC. The photonic die is attached and electrically connected to the integrated switch ASIC.
