Reverse time-lens

We have designed and developed a reverse Electro-Optic Modulator (EOM) based time-lens. Our setup enables radio-frequency (RF) signal modulation driven by an optical input, effectively performing a temporal Fourier transform on the RF signal. In this research, we numerically simulate and experimentally demonstrate the dynamics of such lens. Owing to the unique design of our lens, we further demonstrate that the lens can operate as a quantum element, by sending a squeezed pump as the optical input.
