- *Abstract
-
- *Background
- Photonic solutions for microwave filters offer substantial advantages over electronic implementations, such as wider operating bandwidth and immunity to electromagnetic interference. Although photonic processing of microwave signals has been explored, previous reported approaches have limited filtering functions including low spectral range of several gigahertz, non-flat-topped, high side lobes, high complexity, and limited reconfigurability.
