Abstract

Open-loop spatio-spectral control of broadband light transmission through complex media such as optical multimode fiber (MMFs) requires a priori knowledge of the multispectral transmission matrix (msTM). However, acquisition of msTMs generally requires dense sampling at multiple wavelengths over the operating spectrum. Here we report on a computational spectral memory effect in a 1m long MMF. We demonstrate that the spectral correlation length among the spectral channels of a msTM can be extended 50-fold using a constant correction matrix between adjacent channels. This insight may stimulate efficient multispectral calibration methods that mitigate physical measurement limitations.
