An on-chip optical interconnection structure and network, where the on-chip optical interconnection structure includes M levels of optical switches, and m.sup.th-level optical switches in the M levels of optical switching devices include 2.sup.m-1 optical switches. Each optical switch in (i-1).sup.th-level optical switches in the M levels of optical switches is coupled to two optical switches in i.sup.th-level optical switches. Two optical switches in the i.sup.th-level optical switches coupled to a same optical switch in the (i-1).sup.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.
