Abstract -- A system of delay differential rate equations is introduced as a tool to investigate switching dynamics induced by on-chip filtered feedback in Photonic Integrated Circuits. We show different switching mechanisms between lasing modes that can be induced by modulation of the frequencies of the feedback filter. Finally a novel integrated tunable laser is presented which operates according to such control scheme.
