Metamaterials for future information and

computer technologies.


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.

Our Super Goal


NV-centers in 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)


First Single Photon Source


Prototype Shortcomings:

Wavelength 700 nm

Spectral width (FWHM) lOOnm Frequency =150 kHz

Unpolarised output

Continuous pumpingresults in low efficiency

Nondirectional and unpolarized radiation from nanodiamonds results in low efficiency, that is only small part of emitted photons are flying to consumer

Optical fiber toconsumer

Single photon emission rate is limited by lifetime of excited state and small power of continuous pumping

Large size of fibers (> 10 µm) does not allow to integrate this source on nanochip

20 0.1g


Our device has no these limitations

Prototype Our SourceWavelength 700 nm Wavelength 700 nm

Spectral width (FWHM) lOOnm Spectral width (FWHM) > 2OOnm (due to broadband HMM)

Frequency =150 kHz Frequency =10GHz (due to high density of statesof HMM)

g(2)(0)<0.1 g(2)(0)<0.05 due to pulsed pumping and HMM

Unpolarized output Polarized output Due to HMM anisotropy

Very low efficiency Very high efficiency due to directivity and pulsed pumping

Large size does not allow to speak about nanointegration AT ALL

The design implies the integration on nanochips


Operation principle of 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 plasmonic nanoantennas 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!!!

Spontaneous emission time ( >10ns).Usually it is impossible to control this time and properties of emitted photonMinimal time between

single photons in prototype

Excitation time(depends on laser)


First experimental evidence of spontaneous life time reduction by HMM

(Appl Phys B (2010) 100: 215–218)


Novel excitiong confirmation of our idea Nanodiamonds on HMMNanodiamonds on cover glass

Enhancement factor is greater than 20 now!!!

Lifetime21 ns

Lifetime1 ns


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.

Sufficient funding will definitely allow us to reach our goal and to provide increasing in

SPS emission rate by factor 100 and even more.


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 plasmonic nano-antennas and hyperbolic metamaterials (HMM) etc.

Optical pumping by ps pulse of SPECIAL shape results in decreasing of g(2)(0) and in increasing of energy efficiency.

Operation principle of our single channel SPS (I stage)

Diamond nano crystall (4-5nm) with с NV-center.

Hyperbolic metamaterial

Directed and polarized single photon generated with the help of HMM and nano-antenna.

Plasmonic nano -waveguide or antenna bring photon to optical or quantum computer or to other consumers.

Plasmonic nano-antenna will increase pumping efficiency and directivity of radiation . It also allows us to control time of emission.


II stage ( 2 - 3 years) is development stage. Functioning nanosized SPS prototype will be builtCost 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).

Key features of our SPS• Making use of NV-center in nanodiamonds as stable

source of photons.

• Making use of nanoantennas and hyperbolic metamaterials as 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.
