Title: Mohamed S. Abdelkhalik: Semiconductor Light-Emitting Device Innovations

Introduction

Mohamed S. Abdelkhalik is an inventor associated with Eindhoven, the Netherlands. His patent work includes semiconductor light-emitting devices designed to improve how light is reflected and directed within a device. The supplied information lists 3 patents.

Latest Patents

One of Abdelkhalik’s latest patents, “Semiconductor Light-Emitting Device with Near-Field Surface-Lattice-Resonance Reflector,” describes a device combining a semiconductor diode structure with a surface-lattice-resonance structure and a reflector. The design uses scattering elements to redirect light traveling laterally through the device toward its exit surface, supporting more perpendicular light emission.

Another patent, “Semiconductor Light-Emitting Device with Near-Field Multi-Layer Reflector,” describes a diode structure paired with a reflector made from multiple dielectric layers with different refractive indices. Positioned near the active layer, the reflector returns light into the device, while optional scattering elements can redirect laterally traveling light toward the exit surface.
