Abstract :
The fabrication process of submicrometre parallelogramic-shaped gratings is reported, which involves an image reversal resist process and a novel oblique reactive ion etching (RIE) configuration. A submicrometre parallelogramic grating with 40° blaze angle is fabricated using this method
