“…This concept was first proposed in quantum systems, where the electron wave function exhibits localization within the continuous spectrum of propagating waves [49,50]. Recently, BICs have also attracted considerable attention in photonics [51][52][53]. Mathematically, the BICs show infinite Q-factors, where the optical energy is trapped without leakage [54,55].…”

Many applications of metasurfaces require an ability to dynamically change their properties in the time domain. Electrical tuning techniques are of particular interest, since they pave a way to on-chip integration of metasurfaces with optoelectronic devices. In this work, we propose and experimentally demonstrate an electro-optic lithium niobate (EO-LN) metasurface that shows dynamic modulations to phase retardation of transmitted light. Quasi-bound states in the continuum (QBIC) are observed from this metasurface. By applying external electric voltages, the refractive index of lithium niobate (LN) is changed by Pockels EO nonlinearity, leading to efficient phase modulations to the transmitted light around the QBIC wavelength. The EO-LN metasurface developed in this study opens up new routes for potential applications in the field of displaying, pulse shaping, and spatial light modulating.lithium niobate metasurfaces, electro-optic modulation, bound states in the continuum, resonance

The photonic router is a key device in optical communication and quantum networks. Here, the results of a study of multi‐channel optical routing using optomechanical multimode interference in an optical microcavity are reported. The optomechanical system used here exhibits multi‐optical modes and a mechanical mode. Optomechanical induced transparency and absorption appear in the system due to the interference between different paths. It is shown that the system can be served as a three‐port routing in the red‐detuned region to rout photons from the input port to an arbitrarily selected output port with high routing efficiency by controlling the parameters corresponding to different interference paths.

“…High-quality whispering gallery mode (WGM) microcavities [39] have potential value in investigating fundamental physics and practical technologies such as cavity optomechanics [40][41][42][43][44][45][46][47][48][49][50][51], low-threshold lasing [52][53][54][55][56][57], quantum sensing [58][59][60][61][62][63][64][65][66], and nonlinear optics [42,[67][68][69][70] due to their ability to enhance light-matter interactions. Characterized by exploring the radiation pressure interaction between optical modes and mechanical modes, optomechanics exhibits rich physical phenomena such as optomechanically induced transparency (OMIT) [41,42,48,71], absorption (OMIA) [48,72,73], and optomechanically induced Faraday effect (OMIFE) [74].…”

Polarization beam splitter (PBS) is a crucial photonic element to separately extract transverseelectric (TE) and transverse-magnetic (TM) polarizations from the propagating light fields. Here, we propose a concise, continuously tunable and all-optical partial PBS in the vector optomechanical system which contains two orthogonal polarized cavity modes with degenerate frequency. The results show that one can manipulate the polarization states of different output fields by tuning the polarization angle of the pumping field and the system function as partial PBS when the pump laser polarizes vertically or horizontally. As a significant application of the tunable PBS, we propose a scheme of implementing quantum walks in resonator arrays without the aid of other auxiliary systems. Furthermore, we investigate the optomechanically induced Faraday effect in the vector optomechanical system which enables arbitrary tailoring of the input lights and the behaviors of polarization angles of the output fields in the under couple, critical couple, and over couple regimes. Our findings prove the optomechanical system is a potential platform to manipulate the polarization states in multimode resonators and boost the process of applications related to polarization modulation.
