We study the evolution of the photonic gap present in TiO2 traces, these structures appear in the Ti-TiO2 interface during titania nanotubes formation. Traces can be modeled like photonic crystal because the dielectric function varies periodically in a bi-dimensional space. We conducted a theoretical study based on experimental measurements in traces of TiO2. The study was developed using a plane wave expansion method. This work is a first attempt to introduce photonic gap engineering, which could have technological interests.
