Abstract
ABSTRACTUsing Plasma Enhanced Chemical Vapor Deposition (PE-CVD) we fabricated silicon rich, light emitting SiNx/SiO2 Thue-Morse (T-M) multilayer structures in order to investigate the generation and transmission of light in deterministic aperiodic dielectrics. We found that light emission is significantly enhanced at the wavelengths corresponding to T-M resonant states with field enhancement, in agreement with optical transmission data. Emission enhancement effects by almost a factor of 6 with respect to a reference homogeneous SiNx dielectric have been experimentally measured. The unprecedented degree of structural flexibility of T-M systems can provide alternative routes towards the fabrication of optically active multi-wavelength photonic devices.
