Abstract
Optical injection into a chaotic laser under feedback is investigated for dimension enhancement. Although injecting a solitary laser is known to be low-dimensional, injecting the laser under feedback is found to enhance the correlation dimension D2 in experiments. Using an exceptionally large data size with a very large reconstruction embedding dimension, efficient computation is enabled by averaging over many short segments to carefully estimate D2. The dimension enhancement can be achieved together with timedelay signature suppression. The enhancement of D2 as a fundamental geometric quantifier of attractors is useful in applications of chaos.
