摘要
High-efficiency (>90%) multilevel grating array illuminators are designed using nonlinear parametric optimization and analysed using rigorous electromagnetic grating theory. Designs with eight and 16 relief depth levels are fabricated in fused silica using reactive ion etching and photolithography with three and four electron-beam generated binary amplitude masks, respectively.
