We demonstrate a reconfigurable $4\times 4$ silicon optical switch network by using an architecture of Half-Crossbar. It has the advantage of flexible scalability and utilizes fewer elements. The proposed switch is composed of six dual-microring resonators tuned by the thermo-optic effect. The footprint is only $176\,\,\boldsymbol {\mu }\mathbf {m}\times 632\,\,\boldsymbol {\mu }\mathbf {m}$ . At the wavelength of 1557 nm, the average insertion loss is smaller than 2.5 dB according to the results of all 24 switching states. Its rising response time is about 4.9 $\boldsymbol {\mu }\text{s}$ . The experiment verified the optical data transmission ability of the proposed switch network.
