Latest Patents
One of Bjorkholm's most notable patents involves the "Light induced etching of InP by aqueous solutions of H.sub.3 PO.sub.4." This innovative method focuses on etching semiconductor crystals, specifically those containing elements like indium and phosphorus. The process highlights the use of an aqueous solution of phosphoric acid or hydrochloric acid while illuminating specific areas of the crystal, allowing for a more rapid etching process at the illuminated locations compared to non-illuminated regions. This approach enables precise groove etching by focusing light on a small spot and moving it across the crystal.
Another groundbreaking patent is related to a "Nonlinear optical device using self-trapping of light." Unlike traditional bistable optical devices that rely on resonant optical cavities, this invention employs a nonlinear medium where the index of refraction increases with light intensity. This configuration allows for the propagation of a laser beam with a nonuniform spatial profile without the limitations imposed by high-finesse cavities, thus enhancing operational effectiveness.
