A broadband photon echo effect in a three level Lambda-type system interacting with two laser fields is investigated theoretically . Inspired by the emerging field of nuclear quantum optics which typically deals with very narrow resonances, we consider broadband probe pulses that couple to the system in the presence of an inhomogeneous control field. We show that ideally, such a setup provides an all-electromagnetic-field solution to implement high bandwidth photon echoes, which are easy to control, store and shape on a short time scale . Numerical results for realistic experimental parameters as well as an extension or our setup for chirped pulses are also presented. Our results may pave the way towards ultrafast processing and high-performance photonic devices.
