Latest Patents

Lannon holds a patent for a "High sensitivity polarized-light discriminator device." This invention provides an improved polarized-light detector device that comprises a photodiode with a first contact on the backside of a light-sensing medium and a second contact on the frontside. A spin filter medium is positioned between the backside of the light-sensing medium and the first contact. The application of a magnetic field aligns the magnetic moments in the spin-filter medium, allowing the device to discriminate between different polarizations of an optical signal. This polarization discrimination is enhanced by introducing a net magnetization into the spin filter medium, enabling selected spin-polarized electrons to be transmitted or deflected.
