Abstract

We experimentally study a semiconductor laser subject to two optical feedbacks in a free space setup. We show that control over the feedback phase is essential to adjust the time delay signature in the chaotic output intensity while affecting also the chaotic bandwidth. By optimizing the feedback phase, the time delay signature can be reduced by a factor of more than 2 while maintaining a large chaotic bandwidth.
