Understanding and controlling spatially multimode noise
Abstract
We develop a theoretical framework for predicting spatial noise dynamics in multimode nonlinear photonics, which we experimentally demonstrate in multimode fibers. This insight enables us to show that by suitably engineering the optical field sent into the multimode fiber with a spatial light modulator, we can strongly control and reduce the quantum noise at the output facet of the fiber.
