Latest Patents

Malmberg holds a patent for an "Ion-implanted multilayer optical interference filter." This invention involves a method of forming a single or multilayer optical interference filter by ion implantation. The process includes implanting nitrogen ions into a single crystal silicon at temperatures ranging from about 600°C to about 1000°C. The implanted ions create buried layers of silicon nitride (Si₃N₄), which have a refractive index significantly different from that of silicon (Si). This difference allows for appreciable multiple reflections of incident light, resulting in interference maxima and minima that can be controlled in both amplitude and wavelength position. The ions can be implanted in layers at varying depths to produce a 'thin film' interference filter. Malmberg's patent is a testament to his innovative approach to optical technology, with 1 patent to his name.
