“…4, where the generated fieldâ 1 propagates along the +z direction andâ 2 along the -z direction. For SPDC with χ (2) nonlinearity, this geometry can be achieved by quasiphase matching [29] to submicron periodicity and driven by a single pump laser beam [30,31,32]. For SFWM driven by χ (3) nonlinearity, the phase matching condition can be satisfied by aligning two coherent driving laser beams [33,26].…”

In this chapter, we review recent advances in generating narrowband biphotons with long coherence time using spontaneous parametric interaction in monolithic cavity with cluster effect as well as in cold atoms with electromagnetically induced transparency. Engineering and manipulating the temporal waveforms of these long biphotons provide efficient means for controlling light-matter quantum interaction at the single-photon level. We also review recent experiments using temporally long biphotons and single photons.

“…Backward OPO describes an interesting three-wave interaction process in a quadratic medium which has the unique property of automatically establishing distributed feedback, thus allowing mirrorless OPO. Mirrorless OPO was theoretically predicted in the early days of nonlinear optics [10], however its experimental demonstration has been reported only in recent years using short-period quasi-phase-matching (QPM) nonlinear crystals [12,13]. Backward parametric interaction is also useful for the generation of entangled twin photons [14].…”

Time-Reversed Optical Parametric Oscillation

In recent works, the idea of time-reversed laser oscillation has been proposed and demonstrated to realize a two-channel coherent perfect absorber [Y.D. Chong et al., Phys. Rev. Lett. 105, 053901 (2010); W. Wan et al., Science 331, 889 (2011)]. Here the time reversal of optical parametric oscillation in a nonlinear χ (2) medium is considered and shown to realize a coherent perfect absorber for colored incident signal and idler fields. A detailed analysis is presented for the time-reversed process of mirrorless optical parametric oscillation in the full nonlinear regime.PACS numbers: 42.65. Yj, 42.65.Ky, 42.65.Sf Introduction. Time-reversal symmetry plays an important role in classical electromagnetic theory and nonrelativistic quantum mechanics [1]. Such a symmetry implies that, if a particular physical process is allowed, then there also exists a time-reversed process, which is obtained by changing the sign of the time variable in the dynamical equations. In recent works, the time-reversed process of laser oscillation has been explored, both theoretically [2] and experimentally [3], and shown to realize a coherent perfect absorber (CPA). Under additional symmetry constraints, the processes of lasing and CPA can even occur simultaneously, and a CPA-laser device can be in principle realized [4,5]. Since in a steady-state process time reversal corresponds to interchanging incoming and outgoing fields, the time-reversed process of a laser instability corresponds to perfect absorption of incoming light fields. Such a phenomenon is rather general and expected to occur for the time reversal of other optical instabilities. Among these, optical parametric oscillation (OPO) provides an important example of instability in nonlinear optics, which is at the core of the operation of such important devices as optical parametric oscillators [6][7][8][9]. In a parametric oscillator at the onset of instability, a pump field at frequency ω 3 propagating in a nonlinear χ (2) crystal generates down-converted fields at frequencies ω 1 (the signal field) and ω 2 = ω 3 −ω 1 (the idler field), provided that the phase matching (momentum conservation) condition is satisfied. Generally, at least one of the signal or idler waves resonates in an optical cavity. In the time-reversed process, exactly the opposite occurs: two coherent signal and idler fields, with appropriate amplitude and phase relationship incident onto the pumped nonlinear crystal, are completely annihilated, thus realizing a kind of "colored" CPA device. While a CPA based on time reversal of a laser usually converts the absorbed light into heat [2,3], in the time reversal of OPO the annihilated photons are converted into light of different frequency (the sum-frequency field). Moreover, since the OPO instability and its time-reversal process are allowed in the same medium, an ordinary OPO device can behave at the instability like a CPA-laser device [4,5], i.e. it can simultaneously emit outgoing colored fields and absorb incoming colored fields with appropriate phase re...

Recent Progress in Lithium Niobate: Optical Damage, Defect Simulation, and On‐Chip Devices

et al. 2019

Lithium niobate (LN) is one of the most important synthetic crystals. In the past two decades, many breakthroughs have been made in material technology, theoretical understanding, and application of LN crystals. Recent progress in optical damage, defect simulation, and on‐chip devices of LN are explored. Optical damage is one of the main obstacles for the practical usage of LN crystals. Recent results reveal that doping with ZrO2 not only leads to better optical damage resistance in the visible but also improves resistance in the ultraviolet region. It is still awkward to extract defect characteristics and their relationship with the physical properties of LN crystals directly from experimental investigations. Recent simulations provide detailed descriptions of intrinsic defect models, the site occupation of dopants and the variation of energy levels due to extrinsic defects. LN is considered to be one of the most promising platforms for integrated photonics. Benefiting from advances in smart‐cut, direct wafer bonding and layer transfer techniques, great progress has been made in the past decade for LNs on insulators. Recent progress on on‐chip LN micro‐photonic devices and nonlinear optical effects, in particular photorefractive effects, are briefly reviewed.
