Abstract: Silicon-based optical phased array (OPA) can achieve full solid-state beam steering, which is a promising solution for next-generation light detection and ranging (LiDAR). As OPA research ...

Abstract: Compared with three-level inverters, four-level inverters need more switching times to balance the dc-link capacitor voltages, lowering the efficiency. This article proposes a four-level ...

Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...
