Abstract
A fabrication method and materials produce high quality aperiodic photonic structures. Light emission can be activated by thermal annealing post growth treatments when thin film layers of SiOand SiNor Si-rich oxide are used. From these aperiodic structures, that can be obtained in different vertical and planar device geometries, the presence of aperiodic order in a photonic device provides strong group velocity reduction (slow photons), enhanced light-matter interaction, light emission enhancement, gain enhancement, and/or nonlinear optical properties enhancement.
