| Research Abstract |
In this study, we have designed a new scattering scheme of biexciton-resonant hyper-parametric scattering (RHPS), which enable us to obtain the degenerated colinear beam of entangled photon-pairs. By constructing the non-degenerated (two colored) pulse system as a pump light of RHPS, the the colinear-beam of entangled photons has been successfully generated in the experiment.
On the other hand, we have designed and constructed 4-photon measurement system for the entangled photons via RHPS. By using the measurement system and precise analysis, the statistics of 1 to 4-photons for the entangled photons from RHPS
has been measured for the first time. From the results, It is clear that the entangled multi-photon pairs are generated by extremely-weak excitation power of 100 uW.
