Inclusion of a mirror based on Fano interference in photonic crystal lasers has shown rich dynamics, including controllable self-pulsing, extraordinary feedback stability and pinned single-mode lasing. The narrowband Fano mirror also results in a strong response to tuning of the nanocavity resonance, so that the Fano laser enables realisation of a variety of on-chip optical pulse generation and manipulation schemes. In this work initial numerical investigations of switching with Fano lasers is presented, demonstrating deterministic generation of optical pulses with pulsewidths in the few ps range at GHz repetition rates, as well as equalisation and transistor-like operation.
