Abstract The advancement of microcomb sources, which serve as a versatile and powerful platform for various time–frequency measurements, have spurred widespread interest across disciplines. Their uses span coherent optical and microwave communicati

We demonstrate an approach to achieve a widely tunable photonic-assisted microwave phase shifter (MPS) based on single polarization multiplexing electro-optic modulator (PM-EOM). The PM-EOM can generate orthogonally polarized and phase coherent optic

A microwave photonic filter (MPF) with complex coefficient based on the frequency transparent magnitude response by independent control of the frequency and power of two stimulated Brillouin scattering (SBS) pumps is proposed and experimentally demon

A novel optical frequency-hopping scheme in wavelength-division multiplexing (WDM) systems is proposed to achieve secure communications with high capacity. Frequency hopping is realized by the hopping of digital signals among different channels. In t

We propose a novel approach for the generation of flat optical frequency comb (OFC) using a single polarization modulator (PolM) and a Brillouin-assisted power equalizer (BAPE). The reference radio-frequency (RF) signal applied to the PolM is provide

We propose an optical vector network analyzer (OVNA) based on single-sideband (SSB) modulation and segmental measurement. The motivation of this work lies in the fact that it is hard for the previous SSB-based OVNA to measure a device-under-test (DUT

We report a photonic approach to generating radio-frequency (RF) waveforms based on a dual-parallel Mach-Zehnder modulator (DPMZM) driven by a sinusoidal RF signal. One of the sub-MZMs (MZM1) of the DPMZM is driven by the sinusoidal RF signal, wherea

We propose a new method to improve the accuracy of an optical vector network analyzer (OVNA) based on stimulated Brillouin scattering (SBS) in a dispersion-shifted fiber (DSF). Generally, the measurement error of the OVNA mainly derives from the beat

We report a new photonic microwave pulse generator using a phase-modulator-based Sagnac interferometer (PM-SI) and wavelength-to-time mapping in a dispersive element. The key significance of the proposed scheme is that the phase of the generated micr

We proposed a new approach to generate full-duty-cycle triangular waveforms using a sinusoidal radio-frequency (RF) signal based on stimulated Brillouin scattering. In order to generate a triangular waveform, the even-order harmonics of the RF signal
