An all-optical scheme for simulating non-Markovian evolution of a quantum system is presented. It uses only linear optics elements and by controlling the system parameters allows one to control the presence or absence of information backflow from the environment. A sufficient and necessary condition for the non-Markovianity of our channel based on Gaussian inputs is proved. Various criterions of detecting non-Markovianity are also investigated by checking the dynamical evolution of the channel.
