Duality Modulation (DM)
|Organization:||Quantum Wave Technologies, California, US|
|I.P. Brief:||QuWT has developed a proprietary radiation processing quantum technology, duality modulation, that selectively depletes or enriches relative energy flux on high wave intensity optical and microwave beams. Depleted beams have a broad range of stealth applications in radar and communications. Enriched beams provide for direct amplification of weak signal beams.|
|Summary of I.P.:||Duality modulation (DM) has applicability in a broad spectrum of technology markets including fiber optic transmission systems, free-space optics (FSO) ground-to-ground transceivers, data processing systems, and military radar. DM substantially decreases the number and cost of needed fiber optic amplifiers by extending the range of fiber transmission and improving the amplifier performance. DM-based FSO transceivers significantly increase reliability and transmission distances providing a rapidly deployed and economical alternative to fiber optic lines. DM provides for uniquely secure quantum encryption of transmitted data that cannot be detected by conventional receivers. The miniaturization of DM amplifiers relative to conventional optical amplifiers also opens up a new market in which these DM amplifiers are optical analogs to transistors in integrated optical circuits. DM depleted microwave beams offer a particular military market advantage in stealthy radar.|

|Keywords:||Duality modulation (DM), enriched radiation, depleted radiation, stealth radar, duality encrypted signals, optical transistor|
|Specific Market:||Telecommunications, military, fiber optics, free-space optics, optical data processors|
|Market Size:||DM has applicability in several large, rapidly expanding markets including $7 billion/yr fiber optic amplifiers, $3 billion/yr free-space optics (FSO) transceivers, information processing systems, and military radar. Transition from electronic to optical|
|State of the Art:||Commercially available fiber optic amplifiers are costly laser devices inherently restricted to specific wavelengths. Most fiber optic lines require multiple booster amplifiers. Conventional radar transmitters have no technology to enable cloaking the energy-signature of an interrogation beam. During the transmission phase, this renders the radar unit vulnerable to detection.|
|Competition:||The proprietary DM technology provides for a secure market niche in multiple areas of application. The unique features and advantages of DM are expected to be instrumental in maintaining those market niches.|
|Figures of Merit:||DM produces radiation with energy flux from ~0.01 to ~100 of normal (relative to wave intensity), respectively for highly depleted and highly enriched beams. For military and information security, high depletion levels are needed in steatlth beam applications. For optical data processing, high enrichment levels produce amplifier gain. |
|Tech. Obstacles:||Several working prototype DM systems have been successfully constructed and operated by QuWT. Maximally achievable depletion and enrichment levels have yet to be determined. For cost effective development and assembly of beta components, such as diffraction gratings and beam couplers, services may be sub-contracted to appropriate optical technology companies.|
|Market Obstacles:||QuWT is in an early stage of development but has verified experimentally that its duality modulation technology has enormous potential in many fields of application. The following milestones focus on the optical amplifier application and are not necessarily chronological.
1. Develop enhanced working prototypes, using seed capital as needed, to demonstrate beam depletion and enrichment, optical amplification and other applications.
2. Extend working prototype units to maximally achievable figure of merit (depletion and enrichment) levels to establish market value.
3. Identify a business entity willing to participate either as an exclusive field-of-use licensee, or as an investor of start-up capital, or in some other type of collaborative agreement to bring selected products to market.
4. Identify potential manufacturers and users of optical amplifiers, to be targeted during marketing as either product purchasers, or as licensees or sub-licensees of the optical amplifier technology.
5. As an alternative strategy, obtain seed and/or start-up capital by identifying a business or government entity willing to enter into an exclusive license in a particular field of use of the technology, with royalties from such a license becoming available for research and development of products in other fields of use.
|Patent Landscape:||QuWT has been very successful in obtaining strong, broadly based patents because duality modulation presents new physical phenomena for which there is no pre-existing body of patents. QuWT continues to build on the currently granted patents with a comprehensive program of new applications.|
|Publications:||The basis for producing DM beams is given in two Physical Review papers, S. Mirell, Phys. Rev. A 50, 839 (1994) and 65, 032102 (2002) and in http://arxiv.org/abs/quant-ph/9911076. The technology of generating and detecting these beams has been demonstrated in working prototype systems operating at optical wavelengths and described in http://arxiv.org/abs/quant-ph/0509028.|
