Abstract

We demonstrate numerically that acoustooptic interaction between two co-propagating modes in an optical fiber can be utilized to obtain positive and negative delays. A single acousto-optic interaction region, and a configuration based on two acousto-optic interaction regions, separated by a section of unperturbed fiber, are simulated. It is found that the delays and advancements can be several pulse lengths in the configuration with two acoustooptic coupling regions separated by a section of unperturbed fiber. These results are not in conflict with relativistic causality, but are a consequence of the difference in group velocity between the two coupled modes.
