Simultaneous 256 WDM Channel Generation using a Single AlGaAsOI Waveguide based Time Lens Source

We demonstrate simultaneous WDM signal generation using time lens based optical Fourier transformation. Using a single AlGaAs on-insulator waveguide, 256 1-Gb/s WDM channels with 14-GHz spacing are generated from 1570-nm to 1600-nm, and transmitted over a 100-km unamplified link.
