Latest Patents

Draper's latest patents showcase his innovative approach to solving complex problems. One of his notable inventions is the anisotropic wet etching method. This method involves the application of an etch-rate reducing liquid that selectively wets the mask, allowing for anisotropic wet etching. In a preferred embodiment, a hydrocarbon liquid film is applied to a masked silica surface, enabling the wet etching of straight silica walls without undercutting the mask. The oil selectively wets the polymer mask but not the silica surface, ensuring that the etching produces straight walls instead of undercutting.

Another significant patent is the method of making an optical fiber with the digestion of retracting particles on the preform. This invention reduces particle contamination in drawing optical fiber by coating the glass preform with a particle-digesting coating before it is introduced into the induction furnace. The coating melts and digests refractory particles, allowing for a low surface concentration that does not substantially change the performance of the drawn fiber. The preferred particle-digesting coating used in this method is lithium tetraborate.
