The authors demonstrate programmable integrated microwave photonic filters with low noise figure and ultrahigh dynamic range, using a combination of modulation transformer and double injection ring resonator in a single photonic chip.
The authors demonstrate programmable integrated microwave photonic filters with low noise figure and ultrahigh dynamic range, using combination of modulation transformer and double injection ring resonator in a single photonic chip. Microwave photonics has adopted a number of important concepts and technologies over the recent pasts, including photonic integration, versatile programmability, and techniques for enhancing key radio frequency performance metrics such as the noise figure and the dynamic range. However, to date, these aspects have not been achieved simultaneously in a single circuit. Here, we report a multi-functional photonic integrated circuit that enables programmable filtering functions with record-high performance. We demonstrate reconfigurable filter functions with record-low noise figure and a RF notch filter with ultra-high dynamic range. We achieve this unique feature 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. Our work breaks the conventional and fragmented approach of integration, functionality and performance that currently prevents the adoption of integrated MWP systems in real applications.
