Thank you for getting in contact with Thorlabs and for delivering this beneficial opinions. While this not a function we at present offer, I'm able to unquestionably pass alongside your ask for for just a polarization-entangled Variation in the SPDC810 to our design and style engineers through our interior suggestion forum for thing to consider as being a future item.

Thanks for reaching out to us using this type of inquiry. Concerning the polarization states, the set of photons are break up by polarization and therefore the wavefunctions can not be prepared of the two states as We've got already "measured" the condition. I will get to out to you personally to discuss the rest of your inquiries.

SPDC: Spontaneous parametric down-conversion, Utilized in quantum optics for creating entangled photon pairs along with other quantum procedures.

The crystal is comprised of alternating domains with oppositely oriented spontaneous polarizations, enabling QPM to correct the section mismatch in nonlinear interactions.

We presented the theoretical notion and 1st experimental demonstration of a novel collinear entangled-photon resource, consisting of one unidirectionally pumped nonlinear crystal. Utilizing the collinear double-downconversion influence in periodically poled crystals, this concept can be used to make each, polarisation- and colour-entangled photon states. Numerical evaluations unveiled a wide range of wavelength pairs this kind of source could create. Within our distinct experimental setup we productively created polarisation-entangled pairs of 904.3 nm and 1293.9 nm wavelength, acquiring coincidence prices of PPKTP Crystal 1200 counts/s/mW and an average visibility of V avg�?�?.

tunability, and spatially characterize the supply with regard to the photon pairs produced in collinear

Comparing our plan While using the former entangled photon resource having a GVM-PPKTP crystal within a calcite beam displacer configuration at telecom wavelength [thirty], our count costs are over 100 moments higher, primarily as a result of our remarkably effective SNSPDs and high-quality alignment in Sagnac-loop.

(a) Variation with the measured coincidences like a purpose with the idler HWP angle in the transmitted arm of your fifty-50 BS once the sign photon is projected in D polarization basis at various crystal temperatures (T), (b) experimentally measured visibility within the $D$ D foundation like a perform of crystal temperature.

Thanks for calling Thorlabs. We can offer the degeneracy temperature for that unit which we discover during the unit's general performance verification.

Down the road, this polarization-entangled photon source will probably be helpful for various apps in quantum information and interaction at telecom wavelengths. As an example, this source is directly applicable to free House quantum vital distribution at telecom wavelengths and small length fiber communications.

Hello there Thomas, thank you for calling Thorlabs. We're about to release the software package with the SPDC810. It should be available to download on this web site quickly, but we don't have a set release day for the time being. I've attained out to you personally straight by using a pre-launch Variation of it.

Thanks for getting in touch with Thorlabs. Our engineers will attain out to you on to examine the opportunity of offering this.
