Title: Debapriya Pal: Semiconductor Light-Emitting Device Innovations

Introduction

Debapriya Pal is an inventor based in Amsterdam, the Netherlands. Her patent work includes semiconductor light-emitting devices designed to improve how light is reflected and redirected within a device. She is associated with 3 patents.

Latest Patents

One of Pal’s latest inventions is a semiconductor light-emitting device with a near-field surface-lattice-resonance reflector. The device combines a semiconductor diode structure with a surface-lattice-resonance structure and a reflector. Its scattering elements redirect laterally propagating light toward the device’s exit surface, helping more light emerge in the desired direction.

Another invention is a semiconductor light-emitting device with a near-field multilayer reflector. It uses layers of dielectric materials with different refractive indices to reflect light within the diode structure. The design may also include scattering elements that redirect laterally propagating light toward the exit surface.
