A novel technique is developed to improve the resolution of two‐photon direct laser writing lithography. Thanks to the high collimation enabled by extraordinary εNZ (near‐zero) metamaterial features, ultrathin dielectric hyper‐resolute nanostructures are within reach. With respect to the standard direct laser writing approach, a size reduction of 89% and 50%, in height and width respectively, is achieved...
The interplay between quantum emitters and plasmonic nanostructures can unlock unprecedented functionalities, potentially useful for novel‐concept photonics. Herein, the design and conceptual implementation of an integrated photonic–plasmonic transistor is reported. A mixed top‐down and bottom‐up nanofabrication approach is used to realize a prototype based on a nano‐guided hybrid system enabling...
