Porous silicon-based two-dimensional photonic crystal for biochemical sensing applications

摘要

Various porous silicon-based photonic device structures has attracted more attention for use as biochemical optical sensors. In this study, we have designed and characterized porous silicon-based two-dimensional photonic crystal waveguide structure as an optical biosensor. Field intensity distribution of two-dimensional photonic crystal waveguide was simulated using COMSOL Multiphysics. When the refractive index changes, the field strength changes greatly. This study lays the theoretical foundation for further work.
