Abstract

We have designed and characterized a novel fractal Cantor multilayer porous silicon photonic crystal with a defect embedded in its middle as an optical sensor for sensing of various chemical and biological species. Compared with the common periodic structure one (such as Bragg) and some aperiodic structure (such as Thue-morse), it is more sensitive because of the lower number of interfaces. This research lays the foundation for design all-silicon sensor for biochemical sensing and can also be good applied in excellent filter.
