Neuromorphic Photonic Integrated Circuits
IEEE Journal of Selected Topics in Quantum Electronics, 2018 This paper reviews some recent progress in the field of neuromorphic photonics, with a particular focus on scalability. We provide a framework for understanding the underlying models, and demonstrate a neuron-like processing device—an excitable laser—that has many favorable properties for integration with emerging photonic integrated circuit platforms.

Ferroelectricity in Single‐Crystalline BaTiO3 Nanodisks on Silicon
Advanced Functional Materials, EarlyView.Ferroelectricity is studied in 20 nm thick single crystalline BaTiO3 nanodisks when scaling their diameter from ≈ 400 down to 100 nm. For 100 nm diameter, the vertical polarization component adopts three distinct patterns, and the lateral one shows a rotational invariance in‐plane, suggesting a combination of center‐type and flux‐closure domains.

Advanced Functional Materials, EarlyView.Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...
