“…Table 1 shows the refractive index and dielectric constant of the materials used in the simulation, where the n e of LN can be substituted into Equation (6) to obtain the relationship between ∆n e and the electric field intensity, so as to obtain the n e under different electric field intensities. The effective refractive index of the waveguide with different electric field intensities can be obtained by using a different n e in the simulation.…”

“…These attributes render diamond an ideal material for integrated nonlinear optical systems in visible and infrared wavelengths [1][2][3]. Additionally, diamond possesses color centers with single-atom properties, enabling consistent single-photon emissions at room temperature, rendering it highly suitable for quantum information applications [4][5][6][7][8]. Diamond showcases notable nonlinear properties, such as the absence of two-photon absorption due to its wide 5.5 eV bandgap and a relatively high nonlinear refractive index (n 2 = 8.2 ± 3.5 × 10 −20 m 2 /W in the telecommunication wavelengths) [9][10][11].…”

This study proposes and simulates a numerical analysis of a diamond racetrack microring resonator on a lithium niobate thin film, operating at a 1.55 µm wavelength. The single-mode conditions, transmission losses, and waveguide dispersions are systematically examined. The microring resonator’s radius and gap size are computed and optimized. The designed racetrack microring resonator exhibits a high quality factor (Q-factor) and a high coupling efficiency of approximately 6100 and 95%, respectively, for the transverse TE mode in the C-band. This study achieves a resonant tunability of 1.84 pm/V near the 1.55 μm wavelength by harnessing the electro-optical effect of lithium niobate.

Nitrogen-vacancy (NV) centers in diamond as ideally individual spin quantum systems can be coherently manipulated by microwave fields. Compared to the traditional method using the IQ (In-phase/Quadrature) mixer with a local oscillator and intermediate-frequency (IF) signals, we report an effective and technically simple method to generate the required microwave field by frequency multiplication and realize coherent manipulation of the NV center’s electron spin. After frequency multiplication, the IF signal can be directly converted to the high-frequency microwave field with adjustable pulse width, frequency, phase, and amplitude. A series of spin dynamics applications such as Rabi oscillation, free induction decay, and spin-locking are executed, which verified its performance and feasibility. Frequency multiplication can overcome the problem of clock synchronization between the local oscillator and IF signal and greatly reduce the complexity of the experimental system. The method can be easily used to realize a more complex quantum control sequence such as dynamic decoupling and extended to a wide range of spin-based quantum information applications in the future.

“…Due to its singularity effect, OVB has a helical phase exp(i lφ ) in the wavefront structure, where l is the topological charge (TC) number which can take any integer value, φ denotes the azimuthal angle and ħ is the Planck constant. Since then, OVB has been widely used in quantum information processing [ 3 , 4 ], quantum entanglement [ 5 ], optical micromanipulation [ 6 , 7 ], optical communication [ 8 , 9 , 10 ] and nonlinear optics [ 11 , 12 ]. Hence, with the increasing demand for practical applications, OVB needs to be further studied: from generating [ 13 , 14 , 15 ] and measuring [ 16 ] to shaping OVB [ 17 ].…”

Integrating multiple independent functions into a single optical component is one of the most important topics in research on photoelectric systems. In this paper, we propose a multifunctional all-dielectric metasurface that can achieve a variety of non-diffractive beams depending on the polarization state of the incident light. Using the anisotropic TiO2 rectangular column as the unit structure, the three functions of generating polygonal Bessel vortex beams under left-handed circularly polarized incidence, Airy vortex beams under right-handed circularly polarized incidence and polygonal Airy vortex-like beams under linearly polarized incidence are realized. In addition, the number of polygonal beam sides and the position of focal plane can be adjusted. The device could facilitate further developments in scaling complex integrated optical systems and fabricating efficient multifunctional components.
