Abstract :
In this letter, we describe the fabrication of double-layered self-aligned silicon photonic crystals (PCs) using directional and isotropic etches. The double-layer PCs represent a step towards practical 3-D PCs based on standard Si processing, and they have several advantageous characteristics compared to single-layer PCs, including higher reflectivity and sharper resonances, as demonstrated both experimentally and by finite-difference time-domain (FDTD) simulations.
