Title: Harold G. Craighead: Innovator in Optical Information Storage
Introduction
Harold G. Craighead is a notable inventor based in Fair Haven, NJ (US). He has made significant contributions to the field of optical information storage and retrieval, holding a total of 4 patents. His work has paved the way for advancements in data storage technologies.
Latest Patents
One of Craighead's latest patents is for an optical information storage and retrieval process. This innovative method employs specially fabricated bodies to store information, such as digital data, at high densities. By etching materials like germanium to create columnar or conical features, he enables the archival storage of densely packed information. The process involves melting these structures in localized areas, allowing for a reflective region to appear, which enhances data retrieval capabilities.
Another significant patent is the refractive index switchable display cell. This display cell features at least two states of different opacity, utilizing materials with variable indices of refraction. When the indices of refraction of the materials are similar, the display becomes transparent. Conversely, when they differ, the display appears opaque or less transparent. This technology has potential applications in various display systems.
