functionalities. However, it introduces challenges in fabrication complexity, interface effects, and material compatibility [26][27]. Lithium niobate film on insulator (LNOI) is a promising photonicplatform due to its large transparency window, strong second-order nonlinear optical properties, and ultralow-loss

expected to improve the LED–detector coupling efficiency. Recently, an integrated photonicplatform consisting of an InGaN/GaN NW LED and a p–n NW photodiode interconnected with a SiNx waveguide was demonstrated [30]. The communication took place in the visible spectral range (λ ≈ 400 nm). This platform
