Abstract

We investigate fluorescence (FL) and spontaneous parametric four-wave mixing (SP-FWM) signals in V-, Λ- and N-type energy level systems by changing the frequency detuning or power of the dressing field in Pr 3+ doped Y 2 SiO 5 at 77 K. The lifetime of the two kinds of signals has been calculated, and the desired experimental results have been obtained. We successfully control the intensity and lifetime of fluorescence and SP-FWM signals by changing the power or frequency detuning of the dressing field. The research has potential applications in optical switches and all optical communication.

Controllable lifetime of fourth-order fluorescence and spontaneous parametric four-wave mixing in Pr^3+:YSO

Changbiao Li, Zihai Jiang, Tao Jiang +4 more

We report the measured dressed lifetimes of fourth-order fluorescence and spontaneous parametric four-wave mixing signals by the perturbation chain method in a two-level and heteronuclear-like molecule system of Pr3+:YSO both in theory and experiment. The lifetime of the fourth-order fluorescence depends on the nonlinear processes in the perturbation chain, and can be modulated by the dark state due to the dressing effect and the induced dipole–dipole interaction by changing the frequency detuning and power of the controlling field. Such results can find potential applications in all-optical communication and optical information processing on photonic chips.

Lifetime Polarization of Dressed Multiorder Fluorescence and Spontaneous Parametric Four-Wave Mixing in Pr $^{3+}$ :YSO

Imran Ali, Wang Ruimi, Changbiao Li +4 more

We investigate lifetime (induced dipole–dipole interaction) of spontaneous parametric four-wave mixing (SP-FWM) and multiorder fluorescence (FL) signals controlled by polarization dressing in a heteronuclear-like molecule system of Pr$^{3+} $:YSO. The comparisons between a lifetime of SP-FWM and multiorder FL controlled by single dressing, double dressing, and triple dressing polarization have been investigated. It is observed that FLs have a stronger dressing effect than SP-FWM. The polarization dressing is more obvious in the intensity signal in the spectral domain than that in the time domain. Such results have potential applications in quantum communication such as optical information storage, routing, and processing on a photonic chip.

Competition between spontaneous parametric four-wave mixing and fluorescence in Pr3+:YSO

Huayan Lan, Changbiao Li, Chengjun Lei +4 more

We report the competition between the spontaneous parametric four-wave mixing and second- or fourth-order fluorescence (FL) signals in Pr 3+ :Y 2 SiO 5 crystal. By changing the powers of controlling fields and blocking different fields, the competitive two signals can be identified through the dressing effect. Meanwhile, the delay of fourth-order FL in the time domain results from splitting the energy level. Such results can find potential applications in optical information storage and processing on a photonic chip.

Seeded spontaneous parametric four-wave mixing and fluorescence of Pr3+:YSO

Huaibin Zheng, Changbiao Li, Huayan Lan +4 more

We demonstrate the seeded spontaneous parametric four-wave mixing (SP-FWM) process associated with the fluorescence signals of Pr 3+ :YSO both theoretically and experimentally. For the first time, the dressed SP-FWM processes are observed by self-dressing and/or external-dressing in this crystal. Various possible amplification processes are discussed by selectively seeding various multi-wave mixing (MWM) signals. Two contributions of the dressing effect and the dipole–dipole interaction to the linewidths of the SP-FWM signal and the conjugate signal of the seeding MWM signal associated with the fluorescence signal have been distinguished. In addition, the Autler–Townes-like (or Autler–Townes) splitting effect of the fluorescence spectrum induced by itself (or external) field and the mutual interaction between two fluorescence signals are investigated which are well explained using the presented theoretical model. Such results can find potential applications in all-optical communication and optical information processing on a photonic chip.

Dressed intensity noise correlation and intensity-difference squeezing of spontaneous parametric four-wave mixing process in a Pr^3+:YSO crystal

Irfan Ahmed, Zhengjun Liu, Yan Pan +5 more

We report dressed intensity noise correlation and intensity-difference squeezing based on spontaneous parametric four-wave mixing (SP-FWM) in Pr³⁺:Y₂SiO₅ crystal both experimentally and theoretically. We found such intensity noise correlation and intensity-difference squeezing can be controlled by using the dressing effect to manipulate the nonlinear optical coefficient of the SP-FWM process. By changing detuning and power of the optical field, we manipulate the nonlinear optical coefficient of the SP-FWM process, thus control the correlation and squeezing. The results show stronger correlation and squeezing with single dressing, while weaker near the resonant point due to destructive double dressing. Furthermore,we observed the dependence of correlation times on the power of dressing field, and explained by the combination of the dressing effect and induced dipole-dipole interaction. We also showed the fourth-order fluorescence signals accompanying with the SP-FWM process.

Ultrafast optical transistor and router of multi-order fluorescence and spontaneous parametric four-wave mixing in Pr^3+:YSO

Feng Wen, Imran Ali, Abdulkhaleq Hasan +4 more

We study the realization of an optical transistor (switch and amplifier) and router in multi-order fluorescence (FL) and spontaneous parametric four-wave mixing (SP-FWM). We estimate that the switching speed is about 15 ns. The router action results from the Autler-Townes splitting in spectral or time domain. The switch and amplifier are realized by dressing suppression and enhancement in FL and SP-FWM. The optical transistor and router can be controlled by multi-parameters (i.e., power, detuning, or polarization).
