Coherence Phenomena in the Phase-Sensitive Optical Parametric Amplification inside a Cavity

et al.

Abstract: We theoretically and experimentally demonstrate coherence phenomena in optical parametric amplification inside a cavity. The mode splitting in the transmission spectra of a phase-sensitive optical parametric amplifier is observed. Especially, we show that a very narrow dip and peak, which are the shape of a delta function, appear in the transmission profile. The origin of the coherence phenomenon in this system is the interference between the harmonic pump field and the subharmonic seed field in cooperation wi… Show more

“…In fact, G= is equal to jb=b t j, where b t is the value of the pump amplitude at the threshold of oscillation. The chosen values of G are in the same range as used in the experiment [11]. Evidence of quantum interferences in fluctuations of the output is clearly seen.…”

We report interferences in the quantum fluctuations of the output of a parametric amplifier when the cavity is driven by a quantized field at the signal frequency. The interferences depend on the phase fluctuations of the input quantized field and result in splitting of the spectrum of the output, and thus the recent observation [H. Ma et al., Phys. Rev. Lett. 95, 233601 (2005)] of interferences in the classical domain have a very interesting counterpart in the quantum domain. The interferences can be manipulated, for example, by changing the amount of squeezing in the input field. DOI: 10.1103/PhysRevLett.97.023601 PACS numbers: 42.50.Lc, 42.50.St, 42.65.Lm In recent times quantum interferences have been central to many new applications of few level quantum systems driven by the coherent fields. In particular, the electromagnetically induced transparency (EIT) has led to the possibilities of enhanced nonlinear optical phenomena [1], ultraslow light [2], storage and stopping of light [3], an efficient method of laser cooling [4], and control of chiral anisotropies [5]. The EIT has also been demonstrated for quantized fields [6]. In this Letter we report the possibility of quantum interferences in totally different class of systems which are nonresonant and which are being extensively used in the context of quantum imaging and quantum information science [7,8]. We use parametric interactions driven by quantized fields at the signal or the idler frequency. The generated quantum fields in parametric interactions exhibit a variety of interferences depending on the phase fluctuations in the input quantized field [8]. We note that optical parametric interactions have been studied extensively since the classical work of Armstrong et al. [9]. These classical interactions are known to possess unusual properties. Kaplan [10] discovered that under certain conditions on the pump and signal amplitudes, there is no exchange of energy between the pump and signal. There is yet another very interesting situation where by a suitable choice of the phases of the input amplitudes can lead to either purely growing solutions or decaying solutions. To see this consider the classical Hamiltonian for the parametric processwhich in the limit of undepleted pump b leads to a t 1 2 e 2jgjbt a ÿ igb jgbj a y 1 2 e ÿ2jgjbt a igb jgbj a y :Thus by choosing a=a y igb=jgbj one can suppress the growing solution. Yet another very interesting aspect of classical parametric interactions was discovered in a recent letter by Ma et al. [11]. They have studied a variety of interference effects in parametric interactions in a cavity when the cavity is also driven by a field at the signal frequency, i.e., a Þ 0. The interferences arise from the nonzero signal field at the input and the signal field produced by the pump field. Ma et al. in particular reported mode splitting in transmission spectra. All the above remarkable developments refer to the behavior of parametric interactions when all the fields are treated classically. Clearly it is important t...

“…The optical parametric amplifier (OPA) is one of the most important nonlinear and quantum optical devices. Recently, we studied the coherence phenomena in the phase-sensitive degenerate OPA inside a cavity [16,17]. This phenomenon results from the interference between the harmonic pump field and the subharmonic seed field in OPA.…”

“…The absorptive response of an optical cavity for the probe field is changed by optical parametric interaction in the cavity. Agarwal [18] generalized our observation of interferences in the classical domain [16] to in the quantum domain and studied the interferences in the quantum fluctuations of the output fields from a parametric amplifier when the cavity is driven by a quantized field at the signal frequency.…”

“…In the previous works [16,17], we studied the absorptive and dispersive properties of de-generate double-resonant OPA where only the degenerate subharmonic field resonated inside the cavity but the pump field did not. Although in the experiment with double-resonant OPA the mode splitting in the transmission spectra [16] and the M shape in the reflection spectra were observed experimentally [17], the shape of the phase shift of the reflected field was unchanged [17].…”

We investigate experimentally the absorptive and dispersive properties of triple-resonant optical parametric amplifier OPA for the degenerate subharmonic field. In the experiment, the subharmonic field is utilized as the probe field and the harmonic wave as the pump field. We demonstrate that EIT-like effect can be simulated in the triple-resonant OPA when the cavity line-width for the harmonic wave is narrower than that for the subharmonic field. However, this phenomenon can not be observed in a double-resonant OPA. The narrow transparency window appears in the reflected field. Especially, in the measured dispersive spectra of triple-resonant OPA, a very steep variation of the dispersive profile of the subharmonic field is observed, which can result in a slow light as that observed in atomic EIT medium.

Recently, the vectorial nonlinear optical processes driven by spin‐orbit coupling (SOC) light have come to the fore, leading to striking optical phenomena and important applications both in classical and quantum optics. However, research on the SOC‐mediated light‐atom interactions is still in its infancy. Here, the generation and manipulation of SOC mode through a vectorial four‐wave mixing (FWM) process in 85Rb vapor is demonstrated. Under the excitation of two SOC pump beams, multiple FWM paths can be simultaneously established due to the rich atomic Zeeman sublevels coupling with different circularly polarized components of SOC fields. A higher‐order cylindrical or more general SOC FWM signal is observed in the vectorial FWM process, which obeys angular momentum conservation and Gouy phase matching. In particular, quantum interference between different FWM paths plays a crucial role in manipulating the SOC mode of the generated FWM signal, revealing that the conversion of SOC mode is intrinsically quantum. This work provides a pathway toward deeper insight into the vectorial nonlinear optical processes and may advance technology for shaping spatially structured light, which is essential in applications such as nonlinear polarization imaging and the optical communication realm.
