1. A bridge comprising:
a plurality of interfaces comprising four interfaces, wherein:
each interface is an electrical interface configured to connect electrically a respective die to the bridge,
each interface includes a serializer and deserializer for any die connected to the bridge through the interface; and
a photonic network, wherein:
the photonic network includes a directional photonic link from the serializer of each of the four interfaces to the deserializer of each of the remaining three interfaces, whereby the photonic network and the interfaces provide six bidirectional photonic communication paths ending at the four interfaces and every interface of the four interfaces is bidirectionally coupled to every other of the four interfaces.
