Measuring spatial correlations of photon pairs by automated raster scanning with spatial light modulators
نویسندگان
چکیده
We demonstrate the use of a phase-only spatial light modulator for the measurement of transverse spatial distributions of coincidence counts between twin photon beams, in a fully automated fashion. This is accomplished by means of the polarization dependence of the modulator, which allows the conversion of a phase pattern into an amplitude pattern. We also present a correction procedure, that accounts for unwanted coincidence counts due to polarization decoherence effects.

Spatial soliton pairs in an unbiased photovoltaic-photorefractive crystal circuit
: Optical separate spatial dark and bright soliton pairs in steady-state case in one dimension, for a series circuit consisting of two-photon photorefractive (PR) crystal are investigated. Each crystal can be supported the spatial soliton, and at least one must be photovoltaic. The two solitons are known collectively as separate spatial soliton pairs with dark–dark, bright–dark and bright–brigh...
متن کاملToward real-time quantum imaging with a single pixel camera.
We present a workbench for the study of real-time quantum imaging by measuring the frame-by-frame quantum noise reduction of multi-spatial-mode twin beams generated by four wave mixing in Rb vapor. Exploiting the multiple spatial modes of this squeezed light source, we utilize spatial light modulators to selectively pass macropixels of quantum correlated modes from each of the twin beams to a h...
متن کاملHigh-throughput spatial light modulation two-photon microscopy for fast functional imaging.
The optical monitoring of multiple single neuron activities requires high-throughput parallel acquisition of signals at millisecond temporal resolution. To this aim, holographic two-photon microscopy (2PM) based on spatial light modulators (SLMs) has been developed in combination with standard laser scanning microscopes. This requires complex coordinate transformations for the generation of hol...
متن کاملObservation of quantum entanglement using spatial light modulators.
We use spatial light modulators to observe the quantum entanglement of down-converted photon pairs. Acting as diffractive optical elements within one of the beams, they can be reconfigured in real time to set the spatial profile of the measured mode. Such configurations are highly applicable to the measurement of orbital angular momentum states or other spatial modes, such as those associated w...

We found large cortical territories with EYFP-labeled neurons, which were assumed to also express C1V1T (Fig. 1b). The area with EYFP-expressing cells extended over 1,200 μm, with strongest expression over the central 750-μm zone, particularly in cortical layers 2, 3 and 5. Using two...
