“…In particular,, by exploiting the unprecedented field enhancement in plasmonic structures, nonlinear interactions may be enhanced to remarkable levels 23 . In this context, one should mention that enhancing the interaction of light with thermal alkali vapours can also be achieved by using photonic-guided modes, as demonstrated in hollow core photonic crystal fibres 24,25 , hollow core antireflecting optical waveguides 26,27 , and tapered nanofibres 28,29 .…”

The possibility of combining atomic and plasmonic resonances opens new avenues for tailoring the spectral properties of materials. Following the rapid progress in the field of plasmonics, it is now possible to confine light to unprecedented nanometre dimensions, enhancing light-matter interactions at the nanoscale. However, the resonant coupling between the relatively broad plasmonic resonance and the ultra-narrow fundamental atomic line remains challenging. Here we demonstrate a resonantly coupled plasmonic-atomic platform consisting of a surface plasmon resonance and rubidium ( 85 Rb) atomic vapour. Taking advantage of the Fano interplay between the atomic and plasmonic resonances, we are able to control the lineshape and the dispersion of this hybrid system. Furthermore, by exploiting the plasmonic enhancement of light-matter interactions, we demonstrate alloptical control of the Fano resonance by introducing an additional pump beam.

“…In parallel, several works demonstrated the interaction of thermal alkali vapours with light in guided mode configuration. This includes the use of hollow core photonic crystal fibres13141516 (HC-PCFs), hollow core anti-reflecting optical waveguides171819 (HC-ARROWs), tapered nanofibres202122 (TNFs) and nano waveguides23. In an HC-PCF, alkali vapour is pumped into the core of the fibre and interacts with the electromagnetic field that is guided along the core of the HC-PCF.…”

“…Alternatively, the TNF approach, consisting of solid core fibre surrounded by Rb vapour cladding, was already shown to be useful for nanowatt saturation of the atomic transition20, two photon absorption21 and efficient all-optical switching22. A further step towards miniaturization and integration was accomplished by constructing hollow core waveguides on a chip, via the use of the HC-ARROW1819 approach. This work has the benefit of being both compact and chip-integrable, and enables strong light–matter interaction on chip.…”

Alkali vapours, such as rubidium, are being used extensively in several important fields of research such as slow and stored light nonlinear optics quantum computation, atomic clocks and magnetometers. Recently, there is a growing effort towards miniaturizing traditional centimetre-size vapour cells. Owing to the significant reduction in device dimensions, light–matter interactions are greatly enhanced, enabling new functionalities due to the low power threshold needed for nonlinear interactions. Here, taking advantage of the mature platform of silicon photonics, we construct an efficient and flexible platform for tailored light–vapour interactions on a chip. Specifically, we demonstrate light–matter interactions in an atomic cladding waveguide, consisting of a silicon nitride nano-waveguide core with a rubidium vapour cladding. We observe the efficient interaction of the electromagnetic guided mode with the rubidium cladding and show that due to the high confinement of the optical mode, the rubidium absorption saturates at powers in the nanowatt regime.

“…155 ARROWs can be formed by a low index core layer, which is embedded between higher index layers. This addresses the difficulty of finding suitable optical cladding materials, with a lower refractive index than liquid, making them well suited for optofluidic applications.…”

The advent of optofluidic systems incorporating suspended particles has resulted in the emergence of novel applications. Such systems operate based on the fact that suspended particles can be manipulated using well-appointed active forces, and their motions, locations and local concentrations can be controlled. These forces can be exerted on both individual and clusters of particles. Having the capability to manipulate suspended particles gives users the ability for tuning the physical and, to some extent, the chemical properties of the suspension media, which addresses the needs of various advanced optofluidic systems. Additionally, the incorporation of particles results in the realization of novel optofluidic solutions used for creating optical components and sensing platforms. In this review, we present different types of active forces that are used for particle manipulations and the resulting optofluidic systems incorporating them. These systems include optical components, optofluidic detection and analysis platforms, plasmonics and Raman systems, thermal and energy related systems, and platforms specifically incorporating biological particles. We conclude the review with a discussion of future perspectives, which are expected to further advance this rapidly growing field.
