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.

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
Wavelength 700 nm
Spectral width (FWHM) lOOnm
Frequency =150 kHz
Unpolarised output
Nondirectional and unpolarized
radiation from nanodiamonds results
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

Our device has no these limitations

Our Source
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 states
of HMM)
g(2)(0)<0.05 due to pulsed pumping and HMM
g(2)(0)<0.1
Unpolarized output
Polarized output Due to HMM anisotropy
Very low efficiency
Very high efficiency due to directivity and
pulsed pumping
The design implies the integration on nanochips
Large size does not allow to speak
about nanointegration AT ALL

Operation principle of prototype
Excitation time
(depends on laser)
Minimal time between
single photons in prototype
Spontaneous emission time
( >10ns).Usually it is impossible
to control this time and
properties of emitted photon
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!!!

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.

Operation principle of our single channel SPS (I stage)
Plasmonic nano-antenna will
increase pumping efficiency and
directivity of radiation . It also allows
us to control time of emission.
Diamond nano
crystall (4-5nm)

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

II stage ( 2 - 3 years) is development 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).

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

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.
