Two-order Interference of Single Photon |
|
| Abstract: | A pair of photons called signal and idler photons, respectively, are produced through the nonlinear process of type I spontaneous parametric down conversion in BBO crystal pumped by the second harmonic wave of a Ti∶sapphire femtosecond laser pulse. The two order interference phenomenon of the signal photon in Michelson interferometer is observed and give an analysis in detail. |
