Advances in Flat Optics: From Metalenses to High-Volume Manufacturing for Consumer Electronics and Communications Video

Abstract:  Since the demonstration of the generalized laws of refraction for metasurfaces[1] and the first high performance metalenses[2], metaoptics has rapidly progressed from the laboratory to manufacturing, propelled by the vision that the foundries that manufacture ICs will manufacture CMOS compatible flat optics using the same semiconductor technology based on deep-UV lithography.[3,4]  This will impact the consumer electronics market in areas such as smart phones and wearable displays for AR/VR.  Metasurfaces are now on the market through its partnership with STMicroelectronics, marking the introduction of this revolutionary optical technology in real-world devices.[5]  I will also present advances in cm scale achromatic RGB metalenses for VR by inverse design[6] and 10 cm metalenses for space optics consisting of 20  billion metatoms.[7]  A compact and highly integrated metasurface-based inverse designed mode multiplexer that takes three single-mode fiber inputs and converts them into the first three linearly polarized spatial modes of a few-mode fiber with high fidelity the C-band (1530−1565 nm) of fiber optics will be presented.[8]  I will conclude with the report of  hybrid silicon-organic electrooptic metasurface modulators that use Mie resonances for efficient electro-optic modulation at GHz speeds for free-space communications.[9]

Biography:  Federico Capasso is the Robert Wallace Professor of Applied Physics at Harvard University, which he joined in 2003 after a 27 years career at Bell Labs where he did research, became Bell Labs Fellow and held several management positions including Vice President for Physical Research. His research has spanned a broad range of topics from applications to basic science in the areas of electronics, photonics, nanoscale science and technology including plasmonics, metamaterials and the Casimir effect.  He is a co-inventor of the quantum cascade laser; he recently performed the first measurement of the repulsive Casimir force and has been involved in research on plasmonic metasurfaces aimed at engineering the wavefront of light. He is a member of the National Academy of Sciences, the National Academy of Engineering, a fellow of the American Academy of Arts and Sciences; his awards include the King Faisal Prize for Science, the APS Arthur Schawlow Prize, the IEEE Edison Medal, the Franklin Medal, the Berthold Leibinger Zukunftspreis (the future prize), the Julius Springer Prize for Applied Physics, the Jan Czochralski Award of the European Material Research Society for lifetime achievements in Materials Science.
