Photonic integration, advanced functionality, reconfigurability, and high radio frequency (RF) performance are key features in integrated microwave photonic systems that are still difficult to achieve simultaneously. In this work, we demonstrate an integrated microwave photonic circuit that can be reconfigured for two distinct RF functions, namely,...
We experimentally demonstrate the first ever integrated RF photonic front-end capable of simultaneous tunable filtering and phase shifting. We achieve, at the same time, >50 dB notch filtering tunable from 3.9 to 8.1 GHz and tunable 2π phase shift from 12 to 20 GHz, with an optimized noise figure of 24 dB and a spurious-free dynamic range of 105 dB...

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 i...
Coherent optomechanical interaction known as stimulated Brillouin scattering (SBS) can enable ultrahigh resolution signal processing and narrow-linewidth lasers. SBS has recently been studied extensively in integrated waveguides; however, many implementations rely on complicated fabrication schemes. The absence of SBS in standard and mature fabrica...

Coherent optomechanical interaction between acoustic and optical waves known as stimulated Brillouin scattering (SBS) can enable ultra-high resolution signal processing and narrow linewidth lasers important for next generation wireless communications, precision sensing, and quantum information processing. While SBS has recently been studied extensi...
We demonstrate a reconfigurable filter based on the stimulated Brillouin scattering (SBS) effect in fiber with 3 dB bandwidth from 20 to 500 MHz. We analyze the influence of pump lines and pump spacing on the filter and propose an SBS‐based filter with low passband fluctuation by vectorial modulating multi‐lines pumps. The filter passband fluctuati...
Integrated microwave photonics (MWP) is a fast growing area where high frequency microwave signals are processed in the optical domain, merging key advantages of both microwave photonics and photonic integrated circuits (PICs) technologies including low-loss, reconfigurability, advanced functionality, enhanced stability, and reduced footprint. Plen...
We demonstrate for the first time, to the best of our knowledge, an on-chip microwave photonic (MWP) notch filter with high stopband rejection and integrated optical carrier suppression in a phase modulator-based system. The notch filter was achieved through phase modulation to intensity modulation (PM-to-IM) transformation and dual-sideband-proces...
An on-chip linearization method for phase modulated microwave photonic link based on integrated ring resonators is proposed. By properly tailoring the phase and amplitude of optical carrier band and second-order sidebands, the third-order intermodulation distortion (IMD3) components can be suppressed. Theoretical analysis are taken and a proof-of-c...
Integrated microwave photonic (MWP) is a rapidly growing field where high frequency microwave signals are processed in the optical domain, bringing key advantages of both microwave photonics and integrated optics technologies including low-losses, reconfigurability, advanced functionality, enhanced performance, and reduced footprint. The MWP spectr...
We discuss a new concept in integrated microwave photonics (MWP) aiming at complex phase and amplitude tailoring of RF modulated spectrum for advanced functionalities including modulation transformation and all-optimized MWP filtering.
