“…To excite SPPs on the silver nanowire efficiently and make the nanowire free-standing, we used a fiber taper 31 to connect and lift the silver nanowire. As shown in Figure 1 Additionally, CHSH inequality tests were performed to examine the non-local feature of the output photons.…”

Photonic quantum technologies have been extensively studied in quantum information science, owing to the high-speed transmission and outstanding low-noise properties of photons.However, applications based on photonic entanglement are restricted due to the diffraction limit. In this work, we demonstrate for the first time the maintaining of quantum polarization entanglement in a nanoscale hybrid plasmonic waveguide composed of a fiber taper and a silver nanowire. The transmitted state throughout the waveguide has a fidelity of 0.932 with the maximally polarization entangled state Φ + . Furthermore, the Clauser, Horne, Shimony, and Holt (CHSH) inequality test performed, resulting in value of 2.495 ± 0.147 > 2, demonstrates the violation of the hidden variable model. Since the plasmonic waveguide confines the effective mode area to subwavelength scale, it can bridge nanophotonics and quantum optics, and may be used as near-field quantum probe in a quantum near-field micro/nano-scope, which can realize high spatial resolution, ultra-sensitive, fiber-integrated, and plasmon-enhanced detection.

“…Resonator-type microstructures have been intensively investigated and studied recently in a wide variety of applications including optical filters, sensors and lasers due to the unique low-loss and high quality factor (Q) features [127]. The working principle of the resonator-type microstructures relies on the overlapping and coupling of the evanescent waves of the modes propagating in adjacent turns by coiling the microfiber onto itself.…”

Recent developments in fiber-optic sensing have involved booming research in the design and manufacturing of novel micro-structured optical fiber devices. From the conventional tapered fiber architectures to the novel micro-machined devices by advanced laser systems, thousands of micro-structured fiber-optic sensors have been proposed and fabricated for applications in measuring temperature, strain, refractive index (RI), electric current, displacement, bending, acceleration, force, rotation, acoustic, and magnetic field. The renowned and unparalleled merits of sensors-based micro-machined optical fibers including small footprint, light weight, immunity to electromagnetic interferences, durability to harsh environment, capability of remote control, and flexibility of directly embedding into the structured system have placed them in highly demand for practical use in diverse industries. With the rapid advancement in micro-technology, micro-structured fiber sensors have benefitted from the trends of possessing high performance, versatilities and spatial miniaturization. Here, we comprehensively review the recent progress in the micro-structured fiber-optic sensors with a variety of architectures regarding their fabrications, waveguide properties and sensing applications.

“…With a diameter comparable to the wavelength of light guided within, such ultra-thin optical fibers have intense evanescent fields, which penetrate into the surrounding medium [14]. Being relatively easy to fabricate and integrate with other optical components, nanofibers have emerged as compact, versatile devices with a broad range of applications [15,16], such as cold-atom manipulation [17] and microresonator coupling [18]. For a review on some of this work, the reader is referred to [19,20].…”

Optical Nanofiber Integrated into Optical Tweezers for In Situ Fiber Probing and Optical Binding Studies

Precise control of particle positioning is desirable in many optical propulsion and sorting applications. Here, we develop an integrated platform for particle manipulation consisting of a combined optical nanofiber and optical tweezers system. We show that consistent and reversible transmission modulations arise when individual silica microspheres are introduced to the nanofiber surface using the optical tweezers. The observed transmission changes depend on both particle and fiber diameter and can be used as a reference point for in situ nanofiber or particle size measurement. Thence, we combine scanning electron microscope (SEM) size measurements with nanofiber transmission data to provide calibration for particle-based fiber assessment. This integrated optical platform provides a method for selective evanescent field manipulation of micron-sized particles and facilitates studies of optical binding and light-particle interaction dynamics.
