    • Silicon Metalens Fabrication from Electron Beam to UV-Nanoimprint Lithography 

      Baracu, Angela; Avram, Marius Andrei; Breazu, Carmen; Bunea, Mihaela-Cristina; Socol, Marcela; Stanculescu, Anca; Matei, Elena; Thrane, Paul Conrad Vaagen; Dirdal, Christopher Andrew; Dinescu, Adrian; Rasoga, Oana (Peer reviewed; Journal article, 2021)
      This study presents the design and manufacture of metasurface lenses optimized for focusing light with 1.55 µm wavelength. The lenses are fabricated on silicon substrates using electron beam lithography, ultraviolet-nanoimprint ...

    • Tuning the infrared resonance of thermal emission from metasurfaces working in near-infrared 

      Rasoga, Oana; Dragoman, Daniela; Dinescu, Adrian; Dirdal, Christopher Andrew; Zgura, Irina; Nastase, Florin; Baracu, Angela Mihaela; Iftimie, Sorina; Galca, Aurelian Catalin (Peer reviewed; Journal article, 2023)
      We simulated numerically and demonstrated experimentally that the thermal emittance of a metasurface consisting of an array of rectangular metallic meta-atoms patterned on a layered periodic dielectric structure grown on ...

    • UV-Nanoimprint and Deep Reactive Ion Etching of High Efficiency Silicon Metalenses: High Throughput at Low Cost with Excellent Resolution and Repeatability 

      Dirdal, Christopher Andrew; Milenko, Karolina Barbara; Summanwar, Anand; Dullo, Firehun Tsige; Thrane, Paul Conrad Vaagen; Rasoga, Oana; Avram, Andrei M.; Dinescu, Adrian; Baracu, Angela M. (Peer reviewed; Journal article, 2023)
      As metasurfaces begin to find industrial applications there is a need to develop scalable and cost-effective fabrication techniques which offer sub-100 nm resolution while providing high throughput and large area patterning. ...
