Abstract

We propose an optical time-to-two-dimensional (2-D)-space-to-time-to-2-D-space conversion technique for ultrafast image transmission with ultrashort-pulse lasers. The proposed technique is based on the concepts of the time–space transform, the spatial time–frequency transform, and their inverses. We describe and analyze the proposed technique for ultrafast all-optical processors that can convert an input 2-D spatial object into a modulated ultrafast optical pulse sequence and can retrieve the original 2-D spatial image from the temporal signals transmitted through the optical fiber channel with ultrahigh bandwidth. To verify the proposed technique, we report preliminary experimental results.
