We are interested in the dynamical behaviour of temporal localized states (TLS) and corresponding frequency combs in an injected microcavities subjected to a strong time-delayed feedback. A nonlinear optical system consist of a short injected microcavity with a thin slice of a saturable absorber, coupled to a long external cavity introducing a time delay and closed by a feedback mirror. We disclose sets of multistable bright TLSs coexisting on their respective bistable homogeneous backgrounds and show that they are mainly generated through the locking of domain walls leading to a collapsed snaking structure. The results provide insights into the control and design of emission in delay-coupled micro-resonator systems.
