We count all possible reflections of light paths for different angles of incidence as well as structure's various tilt angles before summing them up together in order to obtain the total reflectivity. We discuss two different light path conditions as follows: 1) the path of light incidence falls perpendicularly onto the edges of the V grooves; 2) the path of light incidence in terms of its horizontal component when it approaches parallel with the edges of V grooves. We use TracePro simulation software in order to verify our analysis. The results from both methods are compatible, enabling us to conclude that light path's geometrical behavior correspond with our analysis of the V-grooved surface. For oblique incident light, V-grooved surface is proved to be effective in reducing the reflectivity for large angles of incidences. © 2011 IEEE. |
