An international team of researchers (the Netherlands, China, Switzerland) has developed a multi-functional photonic integrated circuit that enables programmable filtering functions with record-high performance using versatile complex spectrum tailoring enabled by an all-integrated modulation transformer and a double injection ring resonator as a multi-function optical filtering component. They demonstrated reconfigurable filter functions with record-low noise figure and a RF notch filter with ultra-high dynamic range. According to the researchers their work breaks the conventional and fragmented approach of integration, functionality and performance that currently prevents the adoption of integrated microwave photonic systems in real applications…read more.
