Abstract: (1772 Views)
We analyzed a laser with a mirror realized by Fano interference between the discrete resonance of the nanocavity and continuum of waveguide modes. The steady-state behavior of the photonic crystal Fano laser (PhC-FL) is investigated and shown that by increasing the detuning the output power from cross-port decreases however from through-port increases. In the case of current modulation of the FL, it behaves like a conventional laser and its bandwidth is limited by carrier dynamics limited by relaxation oscillation frequency. It is shown that by increasing the modulation amplitudes the accuracy of the small signal results decreases since it is assumed a very negligible dynamical change around the steady-state point. Furthermore, it is also shown that by increasing the detuning the relaxation oscillation frequency increases.
