Holographic fabrication of graded photonic super-crystals using an integrated spatial light modulator and reflective optical element laser projection system

For the first time, to the best of our knowledge, we have combined a spatial light modulator with a single reflective optical element for the holographic fabrication of graded photonic super-crystals. The hybrid laser projection system takes advantage of the spatial light modulator for pixel-by-pixel phase control and the reflective optical element for large-area, small-feature fabrication. Graded photonic super-crystals with dual period, or with dual period and dual basis, have been fabricated with location dependence across the interference pattern. The fabricated samples have been explained by the simulation of eight-beam interference patterns. (c) 2017 Optical Society of America
