Abstract: An embodiment of the invention includes a memory cell having a magnet layer coupled to a metal layer and read line. The metal layer is also coupled to write and sense lines. During a write operation charge current is supplied to the metal layer via the write line and induces spin current and a magnetic state within the magnet layer based on the spin Hall effect. During a read operation read current is supplied, via the read line, to the magnet layer and then the metal layer and induces another spin current, within the metal layer, that generates an electric field and voltage, based on inverse spin Hall effect, at a sense node coupled to the sense line. The voltage polarity is based on the aforementioned magnetic state. The memory operates with a low supply voltage to drive charge, read, and spin currents. Other embodiments are described herein.

Abstract: An optical switch structure and a method for fabricating the optical switch structure provide at least two ring waveguides located and formed supported over a substrate. At least one of the at least two ring waveguides includes at least one PIN diode integral with the ring waveguide as a tuning component for an optical switch device that derives from the optical switch structure. The PIN diode includes different doped silicon slab regions internal to and external to the ring waveguide, and an intrinsic region there between that includes the ring waveguide. The method uses two photolithographic process steps, and also preferably a silicon-on-insulator substrate, to provide the ring waveguides formed of a monocrystalline silicon semiconductor material.

Abstract: A thermally stabilized, high speed, micrometer-scale silicon electro-optic modulator is provided. Methods for maintaining desired temperatures in electro-optic modulators are also provided. The methods can be used to maintain high quality modulation in the presence of thermal variations from the surroundings. Direct current injection into the thermally stabilized electro-optic modulator is used to maintain the modulation performance of the modulator. The direct injected current changes the local temperature of the thermally stabilized electro-optic modulator to maintain its operation over a wide temperature range.
