Metasurfaces: from Structured Light to Flat Optics
Federico Capasso
Harvard University, USA
ABSTRACT: Subwavelength structured surfaces known as metasurfaces are leading to a fundamental reassessment of optical design with the emergence of optical components that circumvent the limitations of standard ones and with entirely new functionalities such as the ability to shape wavefronts in unprecedented ways by means of flat optics. I will present recent advances on structured light: spin-to-total angular momentum converters (J-plates), which create complex helical beams with potential for applications in quantum optics and other fields, followed by resent research on polarization optics, broad band achromatic planar lenses and wavelength-controlled focusing and orbital angular momentum generation.
BIOGRAPHY: Federico Capasso is the Robert Wallace Professor of Applied Physics at Harvard University, which he joined in 2003 after 27 years at Bell Labs where his career advanced from postdoctoral fellow to Vice President for Physical Research. He has made wide ranging contributions to optics, photonics and nanotechnology, including pioneering the bandgap engineering technique, the invention of the quantum cascade laser, seminal research on metasurfaces, including the generalized Snel’s law and high performance metalenses, and fundamental research on the Casimir effect including the first measurement of the Casmir force. His awards include the Balzan Prize, the IEEE Edison Medal, the American Physical Society Arthur Schawlow Prize in Laser Science, the King Faisal Prize, the SPIE Gold Medal, the AAAS Rumford Prize, the IEEE Sarnoff Award, the Materials Research Society Medal, the Franklin Institute Wetherill Medal, the European Physical Society Quantum Electronics Prize, the Rank Prize in Optoelectronics, the Optical Society Wood Prize, the Berthold Leibinger Future Prize, the Julius Springer Prize in Applied Physics, the Institute of Physics Duddell Medal, the Jan Czochralski Award for lifetime achievements in Materials Science, and the Gold Medal of the President of Italy for meritorious achievement in science.

Fano Photonics for Improving Lasers, Optical Signal Processing and Quantum Technology
Jesper Mørk
Technical University of Denmark, Denmark
ABSTRACT: In this talk I will describe the use of Fano resonances for improving the properties of integrated opto-electronic devices. A Fano resonance arises by the interaction of a continuum of modes and a discrete mode and can be implemented in photonic crystal membranes by coupling line-defect waveguides and point-defect cavities. The resonance can be exploited to realize self-pulsing and ultrafast Fano lasers, non-reciprocal elements, devices for all-optical signal processing, and pulse carvers. Within quantum technology, the Fano resonance may be exploited to suppress de-coherence, e.g. with application in single-photon sources.

Quantum Mechanics with Patterns of Light
Andrew Forbes
University of the Witwatersrand, South Africa
ABSTRACT: In this talk I will provide an overview of recent advances in the field of high-dimensional quantum entanglement and its many applications. I will explore the use of spatial modes of light, patterns of light, as a new basis for encoding information at both the classical and quantum regimes, and show the power this brings for secure and fast communication networks. Finally, I will show how carefully engineered structured light can blur the classical-quantum divide, opening new avenues to explore in the future.

Optoelectronic Properties of Two-Dimensional Transition Metal Carbides (MXenes)
Yury Gogotsi
Drexel University, USA
ABSTRACT: Two-dimensional (2D) materials with thicknesses of a few nanometers or less continue to be explored in optical, photonic, and plasmonic applications due to their diverse properties compared to their bulk counterparts. A large family of 2D materials, known as transition metal carbides and/or nitrides (MXenes), have a general formula of Mn+1XnTx, where M represents a transition metal (Ti, Mo, Nb, V, Cr, etc.), X is either carbon and/or nitrogen, and Tx represents surface terminations. The first discovered and most studied MXene, titanium carbide (Ti3C2Tx), can be produced in large quantities (about 100 g per batch) and high concentrations (up to 100 g/L). In addition, Ti3C2Tx has shown high conductivity at high transparency (10 000 S/cm, >97% transparency per-nanometer), an optical plasmonic peak in near-infrared range (750-800 nm), suggesting it suitable as a photothermal therapy agent, transparent conductor, SERS substrate, as a metamaterial, light to heat transforming material, etc.
With the family of materials containing about 30 different synthesized compositions so far (and millions possible), optimization and light-matter characterization of MXene compositions beyond Ti3C2Tx remains critical. For example, thinner M2XTx MXene structures, such as Ti2CTx, exhibit an optical absorbance peak shift to the visible range (~550 nm), demonstrating the optic/electronic differences from similar-but-thicker structures, such as Ti3C2Tx.6 This talk will provide insight into the optical properties and potential applications of MXenes as well as spectroscopic information which can be applied to designing next-generation photonic and optoelectronic devices, such as photodetectors, random or femtosecond lasers, electro-chromic devices, photonic diodes, metamaterials, and more.

PerovLight: Halide Perovskite Materials for Nanophotonics and Polaritonics
Qihua Xiong
Nanyang Technological University, Singapore
ABSTRACT: Halide perovskite materials have attracted considerable attention recently due to their excellent optical gain properties, balanced electron/hole diffusion, large exciton binding energy and facile synthesis. In this talk, I will discuss our recent effort in probing light-matter interactions in halide perovskite materials from weak coupling regime to strong coupling regime at room temperature towards high performance nanophotonics and polaritonics. I will first introduce vapor-phase grown high quality perovskite crystals for optically pumped photonic lasing based on the intrinsic whispering gallery mode cavity. The lasing quality factor can be as high as 5000 in all-inorganic perovskite crystals. Next, I will present our recent experimental realization of room-temperature polariton lasing in all-inorganic perovskite crystals embedded in two distributed Bragg reflectors. The polariton lasing is evidenced by a superlinear power dependence, macroscopic ground state occupation, and increase of the temporal coherence. Such polariton condensate propagation at room temperature can be further manipulated in 1D perovskite microwires. An ultrafast polariton propagation velocity of > 10 µm/ps was observed at room temperature. Finally, in will introduce our recent breakthrough in perovskite LED devices. Our work advocates the considerable promise of perovskite materials for room temperature nanophotonics and ultrafast polaritonics.
