Fractional Transport of Photons in Deterministic Aperiodic Structures

Abstract The propagation of optical pulses through primary types of deterministic aperiodic structures is numerically studied in time domain using the rigorous transfer matrix method in combination with analytical fractional transport models. We demonstrate tunable anomalous photon transport, includ...
