Photonic Crystal Microring Resonators on a Hybrid Silicon Nitride-on-Lithium Niobate Platform
Zhongdi Peng, Rakesh Krishna, Xi Wu +3
Photonic-crystal resonators (PhCRs) have been widely used in nonlinear integrated photonics for frequency engineering applications. A microwave-assisted frequency converter based o…
Enhanced Polling and Infiltration for Highly-Efficient Electro-Optic Polymer-Based Mach-Zehnder Modulators
Iman Taghavi, Razi Dehghannasiri, Tianren Fan +7
An ultra-narrow slot waveguide is fabricated for use in highly-efficient, electro-optic-polymer-based, integrated-optic modulators. Measurement results indicate that 's below…
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…
