Latest Patents

Vaskin’s listed recent patents focus on near-field reflector structures for semiconductor light-emitting devices.

“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 resonance structure uses scattering elements to redirect light, including light traveling laterally in surface-lattice-resonance modes, toward the device’s exit surface.

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