- Summary
- The spontaneous parametric down-conversion experiment is a quantum optics experiment which demonstrates the very phenomenon of quantum entanglement. The idea of this research project is to conduct this experiment on a self-designed optics system and record observed entangled photon pairs as well as red light cones produced by a non-linear BBO crystal. The BBO crystal is the key component of this experiment and a 405nm laser beam will shine through the crystal to produce down converted 810nm photon pairs. The measuring and data collection tools are a photon counting module and a optics camera. The ultimate goal of this project is to create an optics system and a guide for the spontaneous parametric down-conversion experiment, which will become one of the optics experiments performed in the senior optics lab course. The entire optics system was very successfully built, with the following components aligned in a line: a 405nm laser, a 100mm focus lens, a BBO crystal, a fixed aperture, a red light filter and a camera. The results from the experiment show some indication of the two red light cones produced by the crystal. Further experiments will be carried out to confirm the down-converted light cones and to test the coincidence rate of SPDC.
