“…A coherent interface between mechanics and optics, then, could provide the required quantum links of a hybrid quantum network 6 . Until now, most experiments demonstrating both classical and quantum wavelength conversion have utilized intrinsic optical nonlinearities of materials [7][8][9][10][11][12] . The nonlinear interaction of light with acoustic or molecular mechanical vibrations of materials, for instance, enables a great many optical functions used in highspeed optical communication systems today 8 .…”

Both classical and quantum systems utilize the interaction of light and matter across a wide range of energies. These systems are often not naturally compatible with one another and require a means of converting photons of dissimilar wavelengths to combine and exploit their different strengths. Here we theoretically propose and experimentally demonstrate coherent wavelength conversion of optical photons using photon-phonon translation in a cavityoptomechanical system. For an engineered silicon optomechanical crystal nanocavity supporting a 4-GHz localized phonon mode, optical signals in a 1.5 MHz bandwidth are coherently converted over a 11.2 THz frequency span between one cavity mode at wavelength 1,460 nm and a second cavity mode at 1,545 nm with a 93% internal (2% external) peak efficiency. The thermal-and quantum-limiting noise involved in the conversion process is also analysed, and in terms of an equivalent photon number signal level are found to correspond to an internal noise level of only 6 and 4 Â 10 À 3 quanta, respectively.

Developments in photonic chips have spurred photon based classical and quantum information processing, attributing to the high stability and scalability of integrated photonic devices [1,2]. Optical nonlinearity [3] is indispensable in these complex photonic circuits, because it allows for classical and quantum light sources, all-optical switch, modulation, and non-reciprocity in ambient environments. It is commonly known that nonlinear interactions are often greatly enhanced in the microcavities [4]. However, the manifestations of coherent photon-photon interaction in a cavity, analogous to the electromagnetically induced transparency [5], have never been reported on an integrated platform. Here, we present an experimental demonstration of the coherent photon-photon interaction induced by second order optical nonlinearity (χ (2) ) on an aluminum nitride photonic chip. The non-reciprocal nonlinear optic induced transparency is demonstrated as a result of the coherent interference between photons with different colors: ones in the visible wavelength band and ones in the telecom wavelength band. Furthermore, a wide-band frequency conversion with an almost unit internal (0.14 external) efficiency and a bandwidth up to 0.76 GHz is demonstrated.The importance of integrating nonlinear devices on a photonic chip has become more prominent due to the devices' small foot-prints and large scalability [6,7]. Second order optical nonlinearity (χ (2) ) is one of the most widely explored properties in photonics, utilizing various nonlinear materials [8][9][10][11][12][13]. χ (2) nonlinearity enables the coupling between photons with very different colors, acting as the basis for many important applications such as second harmonic generation, spontaneous parametric down conversion, optical parametric amplification and oscillation. Due to the high quality factor to mode volume ratio, the nonlinear interaction strength is expected to be boosted in optical cavities. Preliminary results in millimeter sized optical resonators have already shown such trend, where efficient second harmonic generation [14,15] and sum frequency generation [16] are demonstrated. However, the realized nonlinear interaction strength on an integrated platform is normally weak, hindered by the challenges of fabricating small size, low loss optical circuits with materials featuring high χ (2) nonlinearity.In this Letter, we demonstrate coherent interaction between photons of different colors on a scalable aluminum nitride-on-insulator [12] chip based on χ (2) optical nonlinearity. The nonlinear optic induced transparency (NOIT), as an analogue to electromagnetically induced transparency resulting from coherent photon-atom [5] or photon-phonon interactions [17][18][19][20], is reported. Due to the inherent phase matching condition, the χ (2) nonlinearity based coherent interaction and the accompanying NOIT phenomenon are non-reciprocal [19,20], which permits future applications such as non-magnetic, ultrafast optical isolators [21][22][23]. We further realize ...

Highly efficient coupling of photons from nanoemitters into single-mode optical fibers is demonstrated using tapered fibers. 7.4 ± 1.2 % of the total emitted photons from single CdSe/ZnS nanocrystals were coupled into a 300-nm-diameter tapered fiber. The dependence of the coupling efficiency on the taper diameter was investigated and the coupling efficiency was found to increase exponentially with decreasing diameter. This method is very promising for nanoparticle sensing and single-photon sources.Collection of fluorescence photons from single nanoemitters is of fundamental importance in fields such as quantum information and biological sensing. For examples, single nanoemitters such
