Reinforcement Learning Enabled Nanophotonic Devices
A reinforcement learning algorithm is used to design photonic devices. The method creates metagratings and grating couplers that efficiently control both the direction and polarization of light. Further, a reinforcement learning approach is used to design in‐plane integrated photonic devices. This approach paves the way for advanced photonic components

Carrier Transport in Electrically‐Driven Photonic Crystal Membrane Lasers
A model to study carrier transport in photonic crystal lasers with a buried heterostructure active region and a lateral current injection scheme is presented. The model identifies unconventional leakage paths which explain low injection efficiencies and enhanced recombination at the p‐doping interface observed experimentally.

The Polarizability Vector: A Polarimetric Observable for Characterizing Anisotropic Nanoparticles
We find an overlooked observable in Nanophotonics that characterizes the optical response of anisotropic nanoparticles from simple polarimetry measurements. ABSTRACT The optical properties of anisotropic nanoparticles (NPs) are often characterized by two principal components of their polarizability tensor.
