A strictly non-blocking 8 × 8 switch for high-speed WDM optical interconnection is realized on InP by using the phased-array scheme for the first time. The matrix switch architecture consists of over 200 functional devices such as star couplers, phase-shifters and so on without any waveguide cross-section. We demonstrate ultra-broad optical bandwidth covering the entire C-band through several Input/Output ports combination with extinction ratio performance of more than 20dB. Also, nanoseconds reconfiguration time was successfully achieved by dynamic switching experiment. Error-free transmission was verified for 40-Gbps (10-Gbps × 4ch) WDM signal.
首次采用相控阵方案在磷化铟（InP）上实现了用于高速波分复用（WDM）光互连的严格非阻塞8×8开关。矩阵开关架构由200多个功能器件组成，如星形耦合器、移相器等，没有任何波导横截面。通过几个输入/输出端口的组合，我们展示了覆盖整个C波段的超宽光带宽，消光比性能超过20dB。此外，通过动态切换实验成功实现了纳秒级的重新配置时间。验证了40 Gbps（10 Gbps×4通道）WDM信号的无差错传输。
