Prototype demonstration of all-optical switches based on laser array

All-optical switches have the advantage of significantly reducing the cost of data-center and improving the transmission characteristics of the system, which has led to many different optical switching technologies for data-center. For this application, we demonstrate a superfast wavelength switching drive design for DFB laser array, and realize a fast tunable laser with 5 ns switching latency. The laser array (C-band, 16-channel, 100 G-space) we used is based on the reconstructed equivalent chirp technology. During the process of tuning, the output wavelength of each channel is within the channel wavelength error range specified by DWDM under the ITU-T standard. Based on the above light source, we build a complete prototype of all-optical switching transceiver integrating transceiver and transmitter, and demonstrate the stable transmission of 10.24 Gb/s data under the condition of four wavelength arbitrary switching and routing.
