Phase Control of Optical Nonreciprocity in Photonic Bandgap Four-Wave Mixing

Abstract

We investigate the optical nonreciprocity induced by the parametrical amplification and the radiation trapping in an atomic photonic bandgap system both theoretically and experimentally. We use two pumping fields to generate entangled photon pairs from spontaneous parametric four-wave mixing, as well as the signals in which they can be enhanced by the feedback dressing effect. Therefore, the frequency difference and the shape change due to this feedback dressing on the two-arm ramps of one round trip are observed. Such optical nonreciprocity can be easily controlled by multiple experimental parameters (frequency detuning, power, and phase) of the dressing beams. In addition, the enhancement and suppression switching induced by the double dressing or triple dressing conditions are also studied. This optical nonreciprocity can contribute to the development of quantum information processing and quantum communications.

Scanning nonreciprocity spatial four-wave mixing process in moving photonic band gap

Hang Wang, Yunzhe Zhang, Mingyue Li +4 more

Abstract We experimentally investigate the scanning nonreciprocity of four-wave mixing process induced by optical parametric amplification in moving photonic band gap, which is different from the propagation nonreciprocity in the optical diode. Meanwhile the frequency offset and the intensity difference are observed when we scan the frequency of the beams on two arm ramps of one round trip. Such scanning nonreciprocities can be controlled by changing the frequency detuning of the dressing beams. For the first time, we find that the intensity difference can cause the nonreciprocity in spatial image. In the nonreciprocity process, the focusing or defocusing is resulted from the feedback dressing self-phase modulation while shift and split is attributed to feedback dressing cross-phase modulation. Our study could have a potential application in the controllable optical diode.

Optical bistablility in six-wave mixing parametrical amplification

Kangkang Li, Renan Bu, Dan Zhang +4 more

We investigate the nonreciprocity "∞"-shape optical bistability (OB) induced by the feedback dressing effect of six-wave mixing parametrically amplified process in a four-level atomic system. Compared to the traditional OB by scanning power, the "∞"-shape OB is scanning probe frequency and demonstrated by "∞"-shape non-overlapping region. More, this non-overlapping region in the x direction (frequency difference) and in the y direction (intensity difference) could demonstrate the degree of this OB phenomenon of dressed probe and conjugate signals, which can be changed by the intensity of feedback dressing. Further, we find the feedback intensity can be controlled by experimental parameters include powers of external-dressing, frequency detuning, incident phase and the nonlinear phase shift of internal-dressing beam. As a result, the nonreciprocity "∞"-shape OB is more sensitive and multiple than traditional OB. These outcomes have potential applications in logic-gate devices and quantum information processing.

Observation of triple-dressing on photonic band gap of optically driven hot atoms

Dan Zhang, Zhiguo Wang, Mengqin Gao +4 more

We experimentally investigate transmission of the probe field, the reflected four-wave mixing photonic band gap signal, and fluorescence signal in a five-level atomic system. In addition, we compared the single-dressing, double-dressing, and triple-dressing on the three types of signals. These three types of signals can be controlled by frequency detunings, powers, and relative phases of the dressing beams. Such a scheme could have potential applications in amplification processing of triode and quantum information processing.

Two-Channel Router of Phase Control Optical Nonreciprocity in Parametric Amplified Four-Wave Mixing

Kangkang Li, Haijun Tang, Irfan Ahmed +5 more

We study the realization of two-channel optical router in parametrically amplified four-wave mixing (PA-FWM) process in rubidium atomic system. Here, we report the first level routing action resulting from the PA-FWM process and the second level routing resulting from the optical nonreciprocity. We also find the channel equalization ratio and optical fidelity of this router can be controlled by the phase of dressing beams. The switching speed of this system is about 18 ns, which can potentially contribute to quantum routing.

Experimental realization of multimode nonlinear parametric amplification from cascading four-wave mixing of dressed atoms

Binshuo Luo, Jin Yan, Yaomin jiang +6 more

The nonlinear parametric process is of great significance for achieving high-quality coherent optical signals and quantum correlated photons. With the development of classical and quantum information processing, the study of the properties of parametric processes is evolving in complex scenarios of multimode, which is limited in conventional nonlinear media due to strict phase matching, e.g. nonlinear crystals. Here we study the dressing-energy-level-cascaded four-wave mixing process to generate multimode optical parametric signals. Via cascading double-Λ type configuration of 85 Rb D 1 line, the non-degenerate energy-level-cascaded FWM is constructed to generate multimode self-parametric amplification. Moreover, with the dressing effects based on atomic coherence, the spatial and frequency multimode characteristics of energy-level-cascaded FWM parametric amplification, i.e., the modes number and pattern, are actively modulated by the pump fields detuning. Also, the spatial modes from the coupling of two coexisting spontaneous parametric FWMs can be controlled to reach tremendous scalability via the atomic coherence and Kerr non-linearity. The atomic coherence effects and unique phase-matching symmetry nature allow flexible modulation of the multimode property of the generated parametric signals within a nonlinear device, which paves a way for multimode classical and quantum information processing.
