“…Photonic crystal microcavities [11] have a hole drilled in the middle of the structure, and a neutral atom located in the hole forms the donor mode geometries with Q � 1.3 × 10 4 . High Q WGM microcavities include microdiscs [15][16][17][18] with Q � 12000 and add/drop flters (semiconductor or polymer) [19,20] with Q � 7000 or Q � 1.3 × 10 5 respectively.

Optical microcavity, which is based on light-matter interaction, has the advantage of high sensitivity as a sensor. It has been widely used in the security, medicine, and environment fields these years. Detection of atoms and molecules at the nanoscale is one of the practical usages of optical microcavity. In this paper, we focus on a ultra-high-quality factor optical microcavity of whispering gallery mode (WGM) to detect the explosive of cyclotrimethylenetrinitramine (RDX). To demonstrate the high sensitivity of the method, we detect the solution at different concentrations. Different types of optical microcavities are suitable for the detection of different matters. Considering the effects of the results and the simplicity of operation, we use silica microspheres chiefly. This is the first time to detect the explosive using highly sensitive optical microcavity. The detection of pure explosives will be helpful for establishing the database of the explosives.

“…In this study, we investigate the properties of photon blockade of a phase-coupled photonic dimer comprising two whispering gallery mode optomechanical resonators and present a general solution for the coefficients of the quantum state. By introducing a tunable coupled structure, we introduce a relatively nonreciprocal phase [41] , [42] , [43] between the two coupled resonators that can be used to tune photon blockade and multiphoton excitation. We believe that the current research has potential theoretical guidance for understanding and utilizing state phases that could further achieve high-precision quantum metrology and quantum telecommunication [44] , [45] .…”

“…Microresonators [ 1–3 ] are key devices for modern photonics toward a large variety of applications, for example, lasers, [ 4–8 ] nonlinear optics, [ 9–14 ] cavity optomechanics, [ 15–19 ] sensing, [ 20–23 ] and quantum information processing. [ 24–28 ] Benefiting from the geometries of microcavities supporting “whispering gallery modes” (WGMs) the light field can be confined in extremely small volumes, reaching very high power density and very narrow spectral linewidth. As a result, the ultrahigh in‐cavity intensities significantly enhance the photon‐to‐photon interactions, leading to ultrahigh efficiencies of nonlinear optical process even at low‐power optical excitation.…”

geometries of microcavities supporting "whispering gallery modes" (WGMs) the light field can be confined in extremely small volumes, reaching very high power density and very narrow spectral linewidth. As a result, the ultrahigh in-cavity intensities significantly enhance the photon-tophoton interactions, leading to ultrahigh efficiencies of nonlinear optical process even at low-power optical excitation. In addition, the small scale enables the construction of resonator-based functional devices with very high integration. With combination of these intriguing features, low-power-consumption, low-cost on-chip devices can be developed successfully. The material platforms for microresonators are crucial for the practical applications. For example, silicon dioxide (SiO 2 ) is considered as one of the most commonly used materials for microresonators, and great success has been achieved based on this easy-to-fabricate platform. [29,30] Recently, with the well-developed technology for on-chip circuits fabrication, some semiconductor materials have been harnessed as the platforms of microresonators for more electro-optic potentials, such as silicon (Si), [31,32] SiC, [33][34][35][36] ZnO, [37,38] GaN, [39,40] or AlN [41,42] . Among them, lithium niobate (LiNbO 3 or LN) has risen into the forefront of microresonator demonstrations and drawn extensive interests in photonics and electronics.Lithium niobate is a multi-functional dielectric crystal that combines a number of excellent features, [43] such as electrooptic, nonlinear optical, acousto-optic, ferroelectric, piezoelectric, photorefractive, photo-luminescent properties, and receives a broad variety of applications in telecommunication, frequency conversion, optical storage, filtering, and quantum photonics. [44][45][46][47] The single-crystal thin film of LN is an ideal platform for microresonators owing to the unique combination of various excellent properties of the bulk. The major obstacle of the LN-based microcavities was the fabrication of high-quality LN thin films because the single-crystalline features cannot be well-preserved in thin-film LN produced by chemical methods of normal deposition that is applied for semiconductors. In addition, large-scale LN-thin film wafers are desired for further processing of on-chip devices. Recently, the so-called "lithium niobate on insulator" (LNOI) technology figures the major problem out and boosts the rapid development of the thin-film LN based devices. [48][49][50][51][52][53] Most used LN films are manufactured by smart " Ion cut" technique. The typical commercialized LN thin film based on ion cut consists of a single-crystalline LN thin film with thickness of 300-900 nm, a cladding layer of SiO 2 with thickness of 2-3 µm, and the supporting material (LN or Si bulk wafer). The fabrication process of ion-cut LN thin film can be referenced in details elsewhere.
