Resum
We study the optical properties of three-dimensional (3D) microstructures fabricated by electrochemical etching of macroporous silicon with modulated pore diameter. Optical measurements along the pore axis reveal photonic band gaps which are also confirmed by calculations of photonic band dispersion. We investigate numerically and experimentally the evolution of these gaps as a function of pore diameter modulation. In addition, a subsequent anisotropic etching of macroporous silicon in alkaline ...
