| Abstract | Coupling molecules to confined electromagnetic fields inside optical microcavities gives rise to hybrid light–matter states known as polaritons, opening new avenues to control chemical phenomena. Recent experiments suggest that strong light–matter coupling can alter photochemical pathways, modify ground-state reactivity, and enhance energy and charge transport—yet the underlying mechanisms remain poorly understood. Here, I will present theoretical advances developed in my group that enable accurate ab initio simulations of molecular response properties and dynamics under strong coupling to quantized radiation fields. These methods provide new insights into how cavity photons reshape molecular dynamical behavior. I will also introduce a recently proposed mechanism that explains changes in ground-state chemical reactivity under vibrational strong coupling. Together, these results offer new theoretical tools and conceptual mechanistic pictures for understanding and predicting polaritonic effects in chemistry, and highlight emerging opportunities for controlling chemical processes with light. |

| Abstract | Silicon photonics has enabled chip-scale devices capable of delivering free-space beams for the detection and manipulation of external objects. Key applications include LiDAR, free-space optical communication (FSO), microscopy, and trapped-ion quantum computing. In the first part of this talk, I will present beam shaping using metasurfaces monolithically integrated with silicon photonic integrated circuits. We experimentally demonstrate diffraction-limited beam focusing and holographic image projection above the silicon photonic chip. Our demonstrations span both the telecommunication wavelength range using the Si platform and the visible wavelength range using the SiN platform. In the second part, I will present two types of silicon photonic beam steerers developed at NYCU for different purposes. The first beam steerer is based on a metalens focal plane array (FPA) and thermo-optic prisms, producing a steerable collimated beam for LiDAR and FSO systems. It features high beam quality, compact footprint, and robust calibration, achieving continuous steering over a large field of view (FOV) of 62° and an average sidelobe suppression ratio of 19 dB. The second beam steer is an 8 8 silicon photonic optical phased array (OPA), producing a focused beam that can be steered throughout a 3D volume. It achieves a lateral FOV of 40 μm 40 μm and a focal length steerable from 250 µm to 450 µm, enabling miniaturized laser-scanning microscopy at chip scale. |
