Abstract
Photorefractive polymers allow to reversibly record holograms over a broad spectral range. This capability offers the possibility to store the information contained in ultrafast optical pulses (i.e., time domain) in the frequency domain. We demonstrate a storage bandwidth of > 80 nm around 800 nm (i.e., > 36 THz), giving a temporal resolution for Gaussian pulses of 13 fs at room temperature. Time reversal of a pulse train of 130 fs pulses confirms these capabilities.
