Abstract:
Optical fiber is a well-established and efficient light-guiding medium. Although optical fiber is efficient for transmitting light, its functionality is limited by the dielectric material of the core, which has poor optoelectronic, magneto-optical, and nonlinear-optical responses and has a dielectric diffraction limit. Therefore, the optical properties of the optical fiber such as phase, amplitude, polarization, and mode profile, cannot be altered after the fiber drawing fabrication, thus limiting the development of novel in-fiber devices. Integration of new materials and nanostructures into fiber will enhance processing/transmission capabilities and novel functionalities.
In this talk, I will present our recent development of “Meta”-optical fiber, an advanced optical fiber integrated with emerging nanophotonic concepts such as optical metasurfaces [1-2], plasmonic nanowires, and zero-index photonics [3-8]. I will present the development of ultrathin optical metalens which is cascaded on the facet of a photonic crystal fiber that enables light focusing. I will also discuss the first experimental demonstration of zero-index resonance excitation in an optical fiber coated with AZO nanolayer and excitation of plasmonic resonances on holey optical fiber for advanced optical sensing and tip-enhanced Raman spectroscopy. These advanced “meta”-optical fibers open a pathway to revolutionary in-fiber optical imaging/endoscopy, lasers/spectroscopies, and optical communication devices.
About our Speaker:
Howard Lee is currently an Associate Professor in the Department of Physics and Astronomy at UC Irvine. Before joining UCI, he was an Associated Professor in the Department of Physics at Baylor University and IQSE Fellow and visiting professor in the Institute for Quantum Science and Engineering (IQSE) at TexasA&M. He was a Postdoctoral Fellow at the Caltech, working with Prof. Harry Atwater in active plasmonics/metasurfaces. He received his PhD in Physics from the Max Planck Institute for the Science of Light in Germany in 2012 under the supervision of Prof. Philip Russell. His work on nano-optics, plasmonics, and photonic crystals has led to 45 journal publications in various journals, such as Science, Nano Letters, and Advanced Materials, as well as 80 invited talks and 150 conference papers. Dr. Lee is a recipient of a 2024 SPIE Fellow, a 2023/2022 Finalist of Moore Inventor Fellow, a 2023 UCI Beall Innovation Award in Physical Sciences, a 2022 iCANX Young Scientist Award, 2021 Finalist of Rising Stars of Light, 2020 SPIE Rising Researcher, a 2020 Baylor Outstanding Professor Award, a 2019 DARPA Director’s Fellowship, a 2019 IEEE OGC Young Scientist Award, a 2018 NSF CAREER Award, a 2017 DARPA Young Faculty Award, a 2018 OSA Ambassador, and a 2017 APS Robert S. Hyer Award.
He organized more than 25 technical sessions in nanophotonics/metasurfaces in international conferences (CLEO, MRS, META, PQE) and serves as Lead Symposium Organizer for plasmonic/metasurface symposiums at 2019-2024 MRS Fall Meeting and 2020-2024 MRS Spring Meeting. He is a Founding Associate Editor for OSA Continuum and Associate Editor for Scientific Reports and Photonics journals. He is a faculty advisor for the Optica/SPIE Student Chapter at UCI and is a Fellow of SPIE.
