In this study. a simplified transformer model is used to predict the beam waist of 1. 092 nm light coupled out from SiN-based mixed pitch gratings at various heights. The beam waists data at various heights above the grating is first compiled. https://www.spidertattooz.com/The-Creme-Shop-X-Hello-Kitty-Pure-Cure-Strawberry-Milk-Toner-Klean-Beauty-p14481/
