A spectrum splitter is an optical device designed to separate light or other forms of electromagnetic energy into its component wavelengths. This process is fundamentally different from a simple power divider, which merely reduces signal strength across multiple outputs. Division is 6 dB from matched ports. 1 dB to 6 dB with a frequency range of 0 Hz to 45 GHz. Shop DigiKey's large in-stock selection of RF Power Dividers/Splitters. However, state-of-the-art solutions typically present trade-offs in terms of loss, bandwidth, and fabrication robustness, especially when targeting multimode. Here we propose and experimentally demonstrate a 3 dB power splitter based on adiabatic mode evolution using a thin-film lithium niobate, with ultra-broadband operation bandwidth from 1200 to 2100 nm.
