Abstract
Spectroscopic properties of the Fabry-Perot (FP) microcavities arranged periodically on a dielectric waveguide are investigated theoretically. A strong coupling behavior between the waveguide resonance and the FP resonance modes is demonstrated for incident light with TE polarization. The narrow-band waveguide resonance modes are observed as asymmetric transmission peaks within the FP stop band, whereas they become transmission dips (antiresonance) in the FP pass band. The coupled mode transits between these two states as the waveguide resonance mode is tuned between the FP pass and stop bands. This transition can be explained in the Fano-picture and is important for the design of photonic devices with narrow-band and tunable optical response.Link to publications or other datasets
