Abstract

Improved switching using Fano resonances in photonic crystal structures - DTU Orbit (25/04/14) Improved switching using Fano resonances in photonic crystal structures - DTU Orbit (25/04/14) Improved switching using Fano resonances in photonic crystal structures We present a simple and robust structure for realizing asymmetric Fano transmission characteristics in photonic crystal waveguide-cavity structures. The use of Fano resonances for optical switching is analyzed using temporal coupled mode theory in combination with three-dimensional finite difference time domain simulations taking into account the signal bandwidth. The results suggest a significant energy reduction by employing Fano resonances compared to more well established Lorentzian resonance structures. A specific example of a Kerr nonlinearity shows an order of magnitude energy reduction.
