The photonic crystal Fano laser is presented, including the laser structure and theoretical model. The model is utilised to investigate numerically the sensitivity of the laser to
external feedback with respect to the stability of the output signal, and the results are compared to the well-known behaviour of conventional Fabry-Perot-type lasers. The conventional operational regimes are observed, including continuous-wave, periodic modulation, pulse generation and chaos. However, it is then demonstrated how the narrowband reflectivity of the Fano mirror works to filter de-stabilising frequency components, leading to significantly better operational stability, so that the sensitivity toward external feedback is drastically improved.
