We analyze the small- and large-signal response of a photonic crystal Fano laser. Conventional current modulation, as well as modulation of the laser via the mirror, is investigated using a numerical approach as well as linear small-signal analysis. The results show that the amplitude modulation bandwidth of one of the laser ports (the through-port) and the frequency modulation bandwidth of another port (the cross-port) extend to the THz region. Large-signal simulations of the laser response to a 500 Gb/s pseudo-random bit sequence modulation of the nanocavity are in good agreement with the predictions of the small-signal analysis. Finally, it is investigated how the design of the Fano mirror, in particular, the quality-factor (Q) of the nanocavity, affects the modulation properties.
