11:00 Invited talk: Integrated single photons sources based on tapered optical nanofibers
Alberto Bramati
Sorbonne Université (France)
We present the optical and quantum properties of highly efficient perovskite nanocubes and discuss our strategy towards a compact integrated single photon source.

11:20 Invited talk: Scalable and efficient photonic designs using disordered metamaterial nanounits
Ekmel Ozbay
Bilkent University (Turkey)
We explored the material and architecture requirements for the realization of light perfect absorption using these metamaterial designs from ultraviolet (UV) to far-infrared (FIR) wavelength regimes. This, in turn, opens up the opportunity of the practical application of these perfect absorbers in large scale dimensions. We adopted these lithography-free techniques in many applications including photoelectrochemical water splitting, photodetection, light emission, sensing, filtering and thermal camouflage.

11:40 Invited talk: Inverse Design of Plasmonic Nano-Antenna
Zhou Zeng, Prabhukumar Venuthurumilli, Xianfan Xu
Purdue University (USA)
We develop a new method for inverse design of plasmonic nano-antennas. We demonstrate the accuracy of this method for a plasmonic antenna used for heat-assisted magnetic recording (HAMR). We also use non-linear material interpolation to counter the non-physical field amplification, and filtering-and-projection regularization to ensure manufacturability of the design. Successful design of a plasmonic aperture to produce an electric field as small as 60 nm x 30 nm is presented.
