  1. Metamaterials for future information and computer technologies.

  2. Our Super Goal To elaborate effective nano-sized single photon sources on demand and to integrate them in nano-chips of optical and quantum computers. Moreover we want to create new market of nano-sized optical and quantum chips.

  3. NV-centersin Diamonds • Stable source of photons • Operation at room temperatures • Relatively simple and cheap manufacturing • Broad operation band width • Great spin decoherence times (1.8 ms)

  4. First Single Photon Source

  5. Prototype Shortcomings: Continuous pumping results in low efficiency Single photon emission rate is limited by lifetime of excited state and small power of continuous pumping Optical fiber to consumer Nondirectional and unpolarizedradiationfrom nanodiamondsresults in low efficiency, that is only small part of emitted photons are flying to consumer Large size of fibers (> 10 µm) does not allow to integrate this source on nanochip

  6. Our device has no these limitations

  7. Operation principle of prototype Spontaneous emission time ( >10ns).Usually it is impossible to control this time and properties of emitted photon Excitation time (depends on laser) Minimal time between single photons in prototype Operation principle of our SPS Making use of HMM allows us to reduce spontaneous emission lifetime by 2-3 ORDERS of magnitude.Making use of ps laser pulse and plasmonicnanoantennas allows us to reduce the pumping time and и g(2)(0)(It is proved in our experiments!). As a result minimal time between emission of single photons can be decreased by several order of magnitude!!!

  8. First experimental evidence of spontaneous life time reduction by HMM (Appl Phys B (2010) 100: 215–218)

  9. Nanodiamonds on cover glass Nanodiamonds on HMM Novel excitiong confirmation of our idea Lifetime 21 ns Lifetime 1 ns Enhancement factor is greater than 20 now!!!

  10. So the preliminary results of 2011 year confirm our idea again. Moreover it was possible to demonstrate increasing in SPS emission rate (number of photons per second) by factor 10 in comparison with previous experiments. Sufficientfunding will definitely allow us to reach our goal and to provide increasing in SPS emission rate by factor 100 and even more.

  11. I stage (1.5 -2 years) is a research stage. The functioning model of SPS device with controllable times of photons emission ( single photon on demand) will be built. Cost of research is $2 million. At this stage the parameters of our SPS will exceed prototype's parameters(emission rate and energy efficiency). The realizability of this stage is based both on experimental demonstration of the effect and our know-how technologies of manufacturing of plasmonicnano-antennas and hyperbolic metamaterials (HMM) etc.

  12. Operation principle of our single channel SPS (I stage) Plasmonicnano-antenna will increase pumping efficiency and directivity of radiation . It also allows us to control time of emission. Diamond nanocrystall(4-5nm) with с NV-center. Directed and polarized single photon generated with the help of HMM and nano-antenna. Plasmonicnano -waveguide or antenna bring photon to optical or quantum computer or to other consumers. Optical pumping by ps pulse of SPECIAL shape results in decreasing ofg(2)(0) and in increasing of energy efficiency. Hyperbolic metamaterial

  13. II stage ( 2 - 3years) isdevelopment stage. Functioning nanosized SPS prototype will be built Cost of development is $5-10 million. Besides single channel SPS, the multichannel chip will be created with full control of emission time in all channels (Single photons on demand).

  14. Operation principle of multichannel SPS (II stage) ps laser pulse of special shape with HORIZONTAL polarization (yellow arrow) will excite only NV center in nanodiamonds with HORIZONTAL antennas attached. Photons will go to consumer over red waveguides ps laser pulse of special shape with VERTICAL polarization (yellow arrow) will excite only NV center in nanodiamonds with VERTICAL antennas attached. Photons will go to consumer over red waveguides Hyperbolic metamaterial

  15. Key features of our SPS • Making use of NV-centerin nanodiamonds as stable source of photons. • Making use of nanoantennas and hyperbolic metamaterialsas emission and photon quality enhancers. • Making use of special shape of ps excitation pulses. • High level integration of nanodiamonds, nanoantennas and nanovaeguides on the metamaterial substrate paves the way to development of quantum and optical nanochips.
