摘要： Embodiments of the present invention relate to an on-chip optical interconnection structure and network. The on-chip optical interconnection structure includes M levels of optical switching devices; and m th -level optical switching devices in the M levels of optical switching devices include 2 m -1 optical switching devices. Each optical switching device in (i-1) th -level optical switching devices in the M levels of optical switching devices is connected to two optical switching devices in i th -level optical switching devices. Two optical switching devices that are in the i th -level optical switching devices and that are connected to a same optical switching device in the (i-1) th -level optical switching devices are connected. The on-chip optical interconnection network is divided into levels, and switching devices connected in a grid manner are formed, so that hierarchical switching may be performed, and conflicts and delays in communication are reduced. In addition, optical switching devices at a bottom layer of the on-chip optical interconnection structure allow faster and more effective communication between computer components without accessing an optical switching device at a higher layer.

The method includes: receiving, by the controller, a request signal sent by a first transmitter, where the request signal is used to request to send an optical signal to a second receiver; establishing, by the controller according to the request signal, by controlling an optical switch in an optical switching network, a second optical path that connects the first transmitter to the second receiver in the optical switching network; 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; and sending, by the controller after or while sending the reset signal, an acknowledgement signal to the first transmitter, where the acknowledgement signal is used to instruct the first transmitter to send, by using the second optical path, an optical signal to the second receiver. In the embodiments of the present invention, the reset signal can be sent to the second receiver in a timely manner, thereby effectively shortening a response time of receiving a new optical signal by the receiver.
