In this study an interesting system in which a bright and dark soliton pulse can be stopped inside a nonlinear waveguide is presented. Here, we propose a system consisting of a series of ring resonators for optical trapping within a nonlinear waveguide. The bright and dark solitons can be controlled and slowed down within the waveguide. The FWHM for the output signals are calculated and used as an optical memory. Bright and dark soliton behaviors within a micro and nano ring resonator are also investigated and described. The required pulse is filtered and amplified, can be controlled and localized within the system. The localized bright and dark solitons are stopped by controlling the input power, which means that the photon stopping can be controlled by light in a ring resonator. © Penerbit UTM Press, Universiti Teknologi Malaysia.

In this study we propose an interesting system in which a bright and dark soliton pulse can be stopped within a nonlinear nanowaveguide. The system consists of micro and nano ring resonators, in which soliton pulse is input into the system and stopped pulse can be achieved within the nonlinear waveguide. A soliton input is chopped by the nonlinear effects into smaller pulses (chaos). The required pulse is filtered and amplified, which can be controlled and localized within the nonlinear waveguide. The localized bright and dark solitons are stopped by controlling the input power, which means that the photons stopping is controlled by light.

Photons trapping within a nano-ring resonator controlled by light

We propose the interesting results that a bright and dark soliton pulse can be localized within a nonlinear nano-waveguide. The system consists of nonlinear micro- and nano-ring resonators, whereas the soliton pulse can be input into the system and trapped within the nano-waveguide. A soliton input is chopped by the nonlinear effects known as chaos into smaller pulses. The required pulse is filtered and amplified, which can be controlled and localized within the nano-waveguide. The localized bright and dark solitons are trapped within a nano-waveguide by controlling the nano-waveguide input power, which means that the photons trapping is controlled by light. © 2009 Elsevier GmbH.

We propose the interesting results that a dark soliton pulse can be localized within a nonlinear nano-waveguide. The system consists of nonlinear micro and nano ring resonators, whereas the dark soliton can be input into the system and trapped within the nano-waveguide. A dark soliton pulse is input into a ring resonator and chopped to be the smaller pulses. The required pulse is filtered and amplified, which can be controlled and localized within the nano-waveguide. The localized bright soliton is also reviewed and discussed. © 2009 Elsevier GmbH.

Quantum information investigation using photons trapped in a fiber optic ring resonator

Photons source generated by light pulses trapping in a fiber optic ring 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. memory time, before the S/N ratio of the detected signal was not valid. Results obtained have shown that number of pulse/photon 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 maintain 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.
