- W3207375561 abstract "As a key component of all-optical switching network terminal technology, ultra-fast wavelength-tunable laser arrays are critical to the high integration and performance improvement of the entire optical switching system. In this article, the array of 2×8 matrix grating DFB laser arrays that we used are based on reconstruction equivalent chirp technology. The wavelength range is in the C-band. Based on this, we designed an excellent control circuit and a high-speed drive circuit for the needs of the laser array to provide the laser array with a drive current that can control the ultra-high-speed switching of channels. The final experimental results show that the channel spacing of the 16 channels of the laser array is 100G, In addition, the switching time of any two channels is less than 10 nanoseconds, and the wavelength selection time has nothing to do with the wavelength range. During the switching process, the centre wavelength drift of each channel is always within the channel wavelength error specified by WDM under the ITU-T standard." @default.
