(a) A typical DLW STED exposure profile: red volume represents standard focusing exciting the material; green represents a phase mask-generated depletion (bottle beam); violet is the resulting modified volume (excitation is minimized by cutting the side and top-bottom lobes with a shaped depletion beam)⁷³. (b) Using the same excitation conditions but increasing the depletion power, the feature size shrinks (from left to right, it is minimized from 220 nm down to 65 nm)⁷³. (c, d) Magnified and full-scale image of 3D chiral polarizer structure fabricated employing simultaneous combination of dip-in⁵⁰ and STED techniques¹¹¹. Reproduced with permission from Refs. 73, 111.
