摘要
Direct pixel-by-pixel phase engineering in a SLM is an effective method for the holographic fabrication of graded photonic super-quasi-crystals with desired disorder and graded photonic super-crystals with rectangular unit-cells. Multiple levels of filling fractions of dielectric in the crystal have been created in the graded regions. Fabrication of these graded photonic super-crystals and super-quasi-crystals with small feature size is possible, using a laser projection system consisting of integrated spatial light modulator and reflective optical element.
