Web11 apr. 2024 · In this work, we experimentally demonstrated that the photoluminescence (PL) from a monolayer of tungsten sulfide (WS 2) could be coupled into a BIC waveguide on a lithium-niobate-on-insulator (LNOI) substrate. WebGrating couplers (GCs) are a kind of critical device for integrated photonics, which connect on- and off-chip devices. In this paper, chirped GCs on Z-cut lithium niobate on insulator were designed and optimized using a backward propagation neural network (BPNN) combined with the particle swarm optimization (PSO) algorithm.
A grating coupler with a high coupling efficiency and low back reflections is designed and demonstrated on the thin film lithium niobate platform, which facilitates an efficient interface between a lithium niobate ridge waveguide and a standard single mode fiber. WebFigure 4: Finite Difference uniform mesh. Formally, we have from Taylor expansion: Subtracting Equation 51 from Equation 51 and neglecting higher order terms: Thus, for TE modes we get. Here we consider: By substituting Equation 55 and Equation 56 into Equation 54, we get: Therefore, we can rewrite Equation 50 for TE modes as.
