This work uses only 1 dB of on-chip stimulated Brillouin scattering gain to create an RF photonic notch filter with 48 dB of suppression, 98 MHz linewidth, and 6 GHz frequency tuning, and establishes the foundation for the first CMOS-compatible high-performance RFPhotonic filter.Abstract:
We demonstrate the first, to the best of our knowledge, functional signal processing device based on stimulated Brillouin scattering in a silicon nanowire. We use only 1 dB of on-chip stimulated Brillouin scattering gain to create an RF photonic notch filter with 48 dB of suppression, 98 MHz linewidth, and 6 GHz frequency tuning. This device has potential applications in on-chip microwave signal processing and establishes the foundation for the first CMOS-compatible high-performance RF photonic filter.read more

TL;DR: In this paper, a chip-based MWP bandstop filter with ultrahigh suppression, high resolution in the megahertz range, and 0-30 GHz frequency tuning is presented. But the performance is limited by trade-offs between key parameters such as tuning range, resolution, and suppression.
