TL;DR: The microparticle velocity is investigated at various laser wavelengths and in various spatial regions of the devices with different resonance quality factors to act as a particle add-drop filter for "particle circuits" in lab-on-a-chip applications.
Abstract: We demonstrate optical manipulation and transport of 1 microm sized polystyrene particles on silicon nitride microring-resonator-based add-drop devices in an integrated optofluidic chip. By tuning the input laser wavelength and upon certain resonance quality factors, we observe microparticles (i) transported to the throughput port, (ii) routed to the microring and trapped in round trips, and (iii) transported to the drop port. We investigate the microparticle velocity at various laser wavelengths and in various spatial regions of the devices with different resonance quality factors. Such a device can act as a particle add-drop filter for "particle circuits" in lab-on-a-chip applications.

TL;DR: In this article, the authors review recent advances in the investigation of optical modes in single three-dimensional whispering gallery microcavities and coupled microresonators, which have the potential for development of single-photon emitters, nanojets, sensors and low-threshold lasers and for fundamental studies of optical matter interactions.
Abstract: We will review recent advances in the investigation of optical modes in single three-dimensional whispering-gallery microcavities and coupled microresonators. Due to the small size and high quality factor these resonators have the potential for development of single-photon emitters, nanojets, sensors and low-threshold lasers and for fundamental studies of optical matter interactions.

TL;DR: In this article, the authors integrated a single-photon source hosted by hexagonal boron nitride (hBN) into a tunable optical microcavity.
Abstract: Sources of pure and indistinguishable single-photons are critical for near-future optical quantum technologies. Recently, color centers hosted by two-dimensional hexagonal boron nitride (hBN) have emerged as a promising platform for high luminosity room temperature single-photon sources. Despite the brightness of the emitters, the spectrum is rather broad and the single-photon purity is not sufficient for practical quantum information processing. Here, we report integration of such a quantum emitter hosted by hBN into a tunable optical microcavity. A small mode volume of the order of $\lambda^3$ allows us to Purcell enhance the fluorescence, with the observed excited state lifetime shortening. The cavity significantly narrows the spectrum and improves the single-photon purity by suppression of off-resonant noise. We explore practical applications by evaluating the performance of our single-photon source for quantum key distribution and quantum computing. The complete device is compact and implemented on a picoclass satellite platform, enabling future low-cost satellite-based long-distance quantum networks.

TL;DR: In this article, the authors introduce the basic physical concepts of cavity optomechanics, and describe some of the most typical experimental cavity optOMEchanical systems for sensing applications, and discuss the noise arising from various sources.
Abstract: The coupling between optical and mechanical degrees of freedom has been of broad interest for a long time. However, it is only until recently, with the rapid development of optical microcavity research, that we are able to manipulate and utilize this coupling process. When a high Q microcavity couples to a mechanical resonator, they can consolidate into an optomechanical system. Benefitting from the unique characteristics offered by optomechanical coupling, this hybrid system has become a promising platform for ultrasensitive sensors to detect displacement, mass, force and acceleration. In this review, we introduce the basic physical concepts of cavity optomechanics, and describe some of the most typical experimental cavity optomechanical systems for sensing applications. Finally, we discuss the noise arising from various sources and show the potentiality of optomechanical sensing towards quantum-noise-limited detection.
