“…Whispering gallery mode (WGM) optical microcavities have been extensively studied due to their extraordinary capabilities of confining and manipulating light in deliberately designed microstructures, [1] which enables great possibilities in fundamental studies such as lightmatter interactions, [2,3] non-Hermitian photonics [4][5][6] as well as highly diverse applications including photonic, [7] optoelectronic, [8] optofluidic, [9] and optomechanical devices. [10] The conventional WGM cavities in a circular shape support co-propagating of clockwise (CW) and counterclockwise (CCW) lightwaves and orthogonal mode families.…”

Dielectric optical microcavities have been explored as an excellent platform to manipulate the light flow and investigate non-Hermitian physics in open optical systems. For whispering gallery mode optical microcavities, modifying the rotational symmetry is highly desirable for intriguing phenomena such as degenerated chiral modes and directional light emission. However, for the state-of-the-art approaches, namely deforming the cavity geometry by precision lithography or introducing local scatterers near the cavity boundary via micromanipulation, there is a lack of flexibility in fine-adjusting of chiral symmetry and far-field emission direction. Here, precise engineering of cavity boundary using electron-beam-induced deposition is reported based on rolled-up nanomembrane-enabled spiral-shaped microcavities. The deformation of outer boundary results in delicate tailoring of asymmetric backscattering between the outer and inner rolling edges, and hence deterministically strong mode chirality. Besides, the crescent-shaped high-index nanocap leads to modified light tunneling channels and inflected far-field emission angle. It is envisioned that such a localized deposition-assisted technique for adjusting the structural deformation of 3D optical microcavities will be highly useful for understanding rich insights in non-Hermitian photonics and unfolding exotic properties on lasing, sensing, and cavity quantum electrodynamics.

“…[ 186 ] In the latest demonstrations of streptavidin detection using surface‐functionalized CROWs, the varying light scattering patterns are recorded and analyzed through a correlation algorithm so that the relative spectral shift can be readily extracted. [ 85,187 ] In this scheme, an on‐chip spectrometer such as an AWG is circumvented, which largely minimizes the sensor footprint and facilitates multiplexed detection on a single chip. As presented in Figure 8e, the miniaturized optofluidic integrated CROW biosensor chip can work with a smartphone camera through a PDMS soft lens as the optical interface, which paves the way toward POC applications.…”

By virtue of the well‐developed micro‐ and nanofabrication technologies and rapidly progressing surface functionalization strategies, silicon‐based devices have been widely recognized as a highly promising platform for the next‐generation lab‐on‐a‐chip bioanalytical systems with a great potential for point‐of‐care medical diagnostics. Herein, an overview of the latest advances in silicon‐based integrated optofluidic label‐free biosensing technologies relying on the efficient interactions between the evanescent light field at the functionalized surface and specifically bound analytes is presented. State‐of‐the‐art technologies demonstrating label‐free evanescent wave‐based biomarker detection mainly encompass three device configurations, including on‐chip waveguide‐based interferometers, microring resonators, and photonic‐crystal‐based cavities. Moreover, up‐to‐date strategies for elevating the sensitivities and also simplifying the sensing processes are discussed. Emerging laboratory prototypes with advanced integration and packaging schemes incorporating automatic microfluidic components or on‐chip optoelectronic devices lead to one significant step forward in real applications of decentralized diagnostics. Besides, particular attention is paid to currently commercialized label‐free optical bioanalytical models on the market. Finally, the prospects are elaborated with several research routes toward chip‐scale, low‐cost, highly sensitive, multi‐functional, and user‐friendly bioanalytical systems benefiting to global healthcare.

Whispering gallery mode resonators (WGMRs) have achieved significant results due to their unique properties such as extremely small mode volume, ultra‐high quality (Q) factor, fast dynamic response, and ultra‐high sensitivity. WGM is commonly used in theoretical physics research, nonlinear optics, optoelectronic devices, and the preparation of high‐sensitivity sensors. This article briefly introduces the basic characteristics and sensing principle of WGM, the manufacturing method of WGMRs, and the sensing applications of microresonators in the fields of physics, chemistry, and biology. The detection limits of physical parameters and the detection sensitivity of biomolecules in recent decades are summarized. In addition, the advantages and disadvantages of different structures and the development trend of WGMRs applications are discussed.
