“…In addition, advanced scalable vdW epitaxy techniques for novel 2D multilayer heterostructures are still required for scalable wafer-level uniformity and high-quality commercial applications. Recently, it was proven feasible to grow hBN layers with controllable thickness on SiO 2 microdisk cavities [209,210]. However, it is necessary to overcome the difficulties in direct growth of 2D materials on 3D irregular NOEMS, including NEM and NOM resonators, nanophotonic cavities, quantum emitters, optoelectronic devices, etc.…”

The discovery of two-dimensional (2D) materials has gained worldwide attention owing to their extraordinary optical, electrical, and mechanical properties. Due to their atomic layer thicknesses, the emerging 2D materials have great advantages of enhanced interaction strength, broad operating bandwidth, and ultralow power consumption for optoelectromechanical coupling. The van der Waals (vdW) epitaxy or multidimensional integration of 2D material family provides a promising platform for on-chip advanced nano-optoelectromechanical systems (NOEMS). Here, we provide a comprehensive review on the nanomechanical properties of 2D materials and the recent advances of 2D-materials-integrated nano-electromechanical systems (NEMS) and nano-optomechanical systems (NOMS). By utilizing active nanophotonics and optoelectronics as the interface, 2D active NOEMS and their coupling effects are particularly highlighted at the 2D atomic scale. Finally, we share our viewpoints on the future perspectives and key challenges of scalable 2D-materials-integrated active NOEMS for on-chip miniaturized, lightweight, and multifunctional integration applications.

“…Growing uniform thin h‐BN‐films via chemical vapor deposition on SiO 2 microdisk cavities enables whispering gallery modes in the hybrid h‐BN‐SiO 2 microdisk with Q‐factors larger 7.6 × 10 5 . [ 108 ] Furthermore, hybrid devices based on van der Waals heterostructures involving h‐BN have been realized. Microdisk cavities fabricated from stacked h‐BN/WS 2 /h‐BN reached an enhanced emission intensity of the WS 2 trion by 2.9 times with a nonlinear power dependence when coupled to the whispering gallery modes.…”

Hexagonal boron nitride is an emerging 2D material with far-reaching applications in fields like nanophotonics or nanomechanics. Its layered architecture plays a key role for new materials such as Van der Waals heterostructures. The layered structure has also unique implications for hosted, optically active defect centers. A very special type of defect center arises from the possibility to host mechanically isolated orbitals localized between the layers. The resulting absence of coupling to low-frequency acoustic phonons turns out to be the essential element to protect the coherence of optical transitions from mechanical interactions with the environment. Consequently, the spectral transition linewidth remains unusually narrow even at room temperature, thus paving a new way toward coherent quantum optics under ambient conditions. In this review, the state-of-the-art of defect centers in hexagonal boron nitride is summarized with a focus on optically coherent defect centers. The current understanding of the defect centers, remaining questions, and potential research directions to overcome pervasive challenges are discussed. The field is put into a broad perspective with impact on quantum technology such as quantum optics, quantum photonics, as well as spin optomechanics.

“…In addition, the undercut techniques used for suspension structure construction and bulk angle etching processes have not been successfully applied to BN [ 5 ]. Recently, researchers have studied the hBN photonic crystal microcavity [ 6 ] and the composite optical microcavity of hBN and SiO 2 [ 7 ], but there is still a research gap in the pure BN microdisk and microring optical microcavity with suspended structure. Management of single-mode laser and nanoscale sensing by optical microcavities in UV has been a great challenge in micro ultraviolet laser and high-sensitivity nano detection.…”

Optical microcavities are known for their strongly enhanced light–matter interactions. Whispering gallery mode (WGM) microresonators have important applications in nonlinear optics, single-mode output, and biosensing. However, there are few studies on resonance modes in the ultraviolet spectrum because most materials with high absorption properties are in the ultraviolet band. In this study, the performance of a microdisk cavity based on boron nitride (BN) was simulated by using the Finite-difference time-domain (FDTD) method. The WGM characteristics of a single BN microdisk with different sizes were obtained, wherein the resonance modes could be regulated from 270 nm to 350 nm; additionally, a single-mode at 301.5 nm is achieved by cascading multiple BN microdisk cavities. Moreover, we found that a BN microdisk with a diameter of 2 μm has a position-independent precise sensitivity for the nanoparticle of 140 nm. This study provides new ideas for optical microcavities to achieve single-mode management and novel coronavirus size screening, such as SARS-CoV-2, in the ultraviolet region.
