MAGTERA-NOVEL SPRINTRONIC DEVICE TERAHERTZ MAGNON LASER

My Note: I came across this interesting webpage today, because it's linked to this blog on it's homepage. The following also caught my eye: "we have invented a novel spintronic device that can generate narrow-band, coherent THz pulses, with tunable frequencies at high efficiency and at power output levels on the order of a milliwatt and greater."

Magtera, Inc. is a privately held Walnut Creek, California based company that has invented and is developing key IP and technology to conquer the last great swath of unoccupied bandwidth in the electromagnetic spectrum - terahertz (THz) spectrum.
The mission of Magtera, Inc. is to enable markets that leverage THz radiation and sensing technologies for security, medical imaging, drug discovery, gene detection, molecular imaging, communication and myriad other applications, and to enable the creation of many more, as yet undiscovered THz-based applications.

Magtera controls the following keys to success:
• Unique enabling technology. Existing THz sources are expensive and inefficient, lack either power or tunability, and none of them can be mass produced on an integrated device. Magtera’s founding inventors conceived of a new device – the Terahertz Magnon Laser, which leverages the quantum magnon laser effect. The Terahertz Magnon Laser is high-power (up to one watt), tunable, compact, capable of large scale production, and can operate at room-temperature.
• Well-developed IP portfolio. The Terahertz Magnon Laser and underlying technology are subject to Magtera’s broad portfolio of patent protection, first filed in 2003 and including eight patents issued in the U.S. and two patents issued in China, with numerous patent applications pending in major markets worldwide.
• Accessible broad market opportunities. Magtera has identified several “killer” applications for its THz technology, such as the portable Terahertz Magnon Laser blood sugar measuring apparatus, which need not pierce the skin. With thirty million diabetics in the U.S. alone, we believe the worldwide market opportunity for such a device is in the scores of billions of dollars.

A. Why THz radiation – and why not yet
The terahertz range of frequencies, generally accepted as being within the frequency region between 3 × 1011 to 3 × 1013 Hz (having wavelength in a vacuum from one millimeter to ten microns), presents a new frontier for solid-state electronics and their application. Since THz radiation spectrum exists between microwave spectrum (used in microwave electronics) and infrared spectrum (used in infrared optics), and corresponds to the molecular vibration frequencies in complicated biological objects, the potential and emerging applications of terahertz electronics are myriad and vast. When adequately supplied and sensed, THz radiation can be used as a powerful tool for through-the-wall imaging, since it can penetrate through thick dry wall and other common building materials. It can also be used to detect threatening munitions from across a battlefield, for bio-molecular sensing and biomedical analysis, to detect poisonous and biological substances, in medicine as a sensor for cancer cells and other real-time diagnostics, for environmental monitoring and radio astronomy, and in semiconductor lithography and a host of security- and defense-related applications.
Despite the opportunities, the lack of a high-power, narrow-band, tunable and portable THz source remains the most significant limitation of modern THz systems. The best current commercially available techniques for generation and modulation of THz radiation use ultra-short optical pulses to generate a very rapid change of the conductivity of a semiconductor sample. These techniques allow one to obtain a broadband, pulsed radiation in the THz range, at power levels on the order of microwatts, but without significant tunability; they provide faint, shotgun energy where highly tuned and high power rifle shots are required.
To come at these problems and opportunities from an entirely new direction, we have invented a novel spintronic device that can generate narrow-band, coherent THz pulses, with tunable frequencies at high efficiency and at power output levels on the order of a milliwatt and greater.
