Abstract

In this work, a new scheme based on a Si₃N₄ microresonator for generating parallel pulsed chaos is proposed, and the performances of the parallel pulsed chaos and its application in imaging are experimentally investigated. Under optical injection with suitable injection parameters, the Si₃N₄ microresonator can output a continuous wave (CW) chaotic microcomb including nearly 100 comb lines. After passing through an acousto-optic modulator, the CW chaotic microcomb can be transferred into pulsed chaotic microcomb, in which each comb line provides a pulsed chaos. Therefore, parallel pulsed chaos signal can be generated. Taken the parallel pulsed chaos signal as the emitting resource of lidar, the quality of imaging has been analyzed. The experimental results show that clear target imaging can be achieved.
