James C North is a notable inventor based in New Providence, NJ, who has made significant contributions to the field of magnetic devices and photodetectors. With a total of four patents to his name, North's work has had a considerable impact on technology and device manufacturing.

Latest Patents

One of his latest patents is focused on magnetic devices and methods of manufacture. This innovation involves magnetic devices exemplified by bubble devices that depend upon functional magnetic layers initially produced by epitaxy. These layers are reduced to effectively thinned surface layers through ion implantation, which occurs at well-defined energy spectral levels. This method minimizes the effect on surface layers while predominantly affecting a 'buried layer', allowing for the creation of high bit density devices with regions less than 3 micrometers in thickness.

Another significant patent is for an edge illuminated photodetector with optical fiber alignment. This silicon photodetector is capable of long wavelength response and includes means for aligning an optical fiber for edge illumination. The design features a silicon body with major surfaces lying in the (110) plane, and a precisely etched groove that ensures vertical alignment of the optical fiber with the detector. This innovation enhances the efficiency of light transmission from the fiber to the detector.
