Abstract: An on-chip optical interconnection structure and network, where the on-chip optical interconnection structure includes M levels of optical switches, and mth-level optical switches in the M levels of optical switching devices include 2m-1 optical switches. Each optical switch in (i-1)th-level optical switches in the M levels of optical switches is coupled to two optical switches in ith-level optical switches. Two optical switches in the ith-level optical switches coupled to a same optical switch in the (i-1)th-level optical switches are coupled. The on-chip optical interconnection network is divided into levels, and switches coupled in a grid manner are formed such that hierarchical switching may be performed, and conflicts and delays in communication are reduced.

Abstract: A signal transmission method includes receiving, by a controller, a request signal sent by a first transmitter. The method includes establishing, by the controller according to the request signal, a second optical path that connects the first transmitter to the second receiver in the optical switching network (OSN). The method includes sending, by the controller, to the second receiver according to the request signal, a reset signal used to instruct the second receiver to be reset to an initial state. The method includes sending, by the controller, an acknowledgement signal to the first transmitter, by using the second optical path, an optical signal to the second receiver.
