Reconfigurable Optical Add-Drop Multiplexers (ROADMs) have been developed to address this, allowing dynamic wavelength routing and network optimization. However, improving their flexibility, reducing insertion losses, and enhancing their spectral efficiency are ongoing areas. Wavelength division multiplexers are fundamental to the functioning and performance of integrated photonic circuits, with applications ranging from optical interconnects to sensing and quantum technologies. Current solutions are limited by trade-offs between channel spacing, crosstalk, insertion. Coarse Wavelength Division Multiplexing (CWDM) increases fiber capacity by combining multiple optical wavelengths, or “channels,” onto a single fiber. Each wavelength transmits an independent data stream, enabling multiple signals to coexist on the same fiber without interference.
