Abstract

Photons source generated by light pulses tapping in a fiber optic rinvg resonator is presented. Light pulses from OTDR were launched into a single mode fiber optic, which was a form of a ring resonator. All fiber optic components were connected and used to realize the practical in quantum information via fiber optic. Light pulses were trapped in the ring resonator in a period of time, i.e. memor time, before the S/N ratio of the detected signal was not valid. Results obtained have shown that number of pulse/phton trains obtained depend on a fiber optic ring resonator length, input pulse width and gain. In applications, the signal amplifier using inline connection with fiber laser could be used to amaintain the required S/N. The attenuation part could be employed into the system to produce a single photon pulse during the circulation in fiber optic ring resonator. The photon visibility in term of polarization extinction ratio of 10 dB is noted.
