|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.
Purdue University researchers have developed a novel method to filter wideband microwave-millimeter wave signals in the optical spectrum. This technology optimizes the performance of a radio receiver. This method enables filter and waveform generation technology for radio frequency applications such as pulsed radar, radio frequency sensing, and electronic countermeasures.
