Multiband Optical Filters Are Telecom Networks' Multitaskers

Author: Rebecca Saaltink and Xiaolun Zeng Wednesday, August 16, 2023
The ability to combine more than one spectral band into a single optical filter can enable flexibility of system design and reduce the number of components and the costs needed to achieve a desired functionality in fiber optic telecom components. Recent advances in multiband and multifunction filters support the development of dual- and multi-bandpass filters for use in the backbone WDM architectures for wireless networks, and enable hybrid GFFs that couple gain-flattening functionality with laser pump blocking to improve performance and save module build costs.
