Ion-Assisted Nanoscale Material Engineering in Atomic Layers
Hossein Taghinejad, Mohammad Taghinejad, Sajjad Abdollahramezani +11
Achieving deterministic control over the properties of low-dimensional materials with nanoscale precision is a long-sought goal. Mastering this capability has a transformative impa…
Electrically driven programmable phase-change meta-switch reaching 80% efficiency
Sajjad Abdollahramezani, Omid Hemmatyar, Mohammad Taghinejad +11
Despite recent advances in active metaoptics, wide dynamic range combined with high-speed reconfigurable solutions is still elusive. Phase-change materials (PCMs) offer a compellin…
Racetrack microresonator based electro-optic phase shifters on a 3C-silicon-carbide-on-insulator platform
Tianren Fan, Xi Wu, Sai R. M. Vangapandu +3
We report the first demonstration of integrated electro-optic (EO) phase shifters based on racetrack microresonators on a 3C-silicon-carbide-on-insulator (SiCOI) platform working a…
Dynamic hybrid metasurfaces
Sajjad Abdollahramezani, Omid Hemmatyar, Mohammad Taghinejad +10
Efficient hybrid plasmonic-photonic metasurfaces that simultaneously take advantage of the potential of both pure metallic and all-dielectric nanoantennas are identified as an emer…
ITO-Based Microheaters for Reversible Multi-Stage Switching of Phase-Change Materials: Towards Miniaturized Beyond-Binary Reconfigurable Integrated Photonics
Hossein Taghinejad, Sajjad Abdollahramezani, Ali A. Eftekhar +6
Inducing a large refractive-index change is the holy grail of reconfigurable photonic structures, a goal that has long been the driving force behind the discovery of new optical ma…
Reconfigurable Multifunctional Metasurfaces Employing Hybrid Phase-Change Plasmonic Architecture
Sajjad Abdollahramezani, Hossein Taghinejad, Tianren Fan +3
We present a hybrid device platform for creating an electrically reconfigurable metasurface formed by the integration of plasmonic nanostructures with phase-change material germani…
