| dc.description | Quantum frequency up-conversion (QFC) of non-classical states of light allows the
integration of different quantum systems working at different energies. This process takes
advantage of telecommunication wavelengths photons for optical fiber transmission of
quantum information, and near visible wavelengths for data manipulation and storage.
The key objective of QFC is to guarantee that the input photon number probability
distribution is maintained after the conversion process. With this, we will be able to
efficiently study the single-photon emission properties of epitaxial InAs/GaAs quantum
dots embedded in a photonic crystal nanocavities without the problems that inefficient IR
wavelengths detectors imply. The up-conversion process consists on combining two
optical fields, in a nonlinear medium, to generate a third field that is equal to the two inputs
frequency sum. To fulfill the momentum conservation, required by this process, we need
to compensate the wave vector mismatch between the output and input beams. This is
achieved by using a grating in the nonlinear medium, a process named quasi-phase
matching (QPM). In this work we use a Zinc doped periodically poled LiNbO3 (Zn:PPLN
WG) waveguide as the nonlinear material. To achieve the quantum frequency conversion
of a semiconductor quantum dot (QD) single photons emission, embedded in a photonic
crystal nanocavity, we started by characterizing the performance of the PPLN-WG in the
optical power macro-regime. Signal photons, produced by an 1175nm laser, simulating
our QD emission line, are combined with pump photons, produced by a C-band laser,
with a dichroic mirror before entering the PPLN waveguide. In order to achieve the phase
matched wavelength in the PPLN, its temperature must be finely tuned. The signal
coming out of the PPLN waveguide is filtered and analyzed. | |
