An approach to performing photonic-assisted temporal convolution of two microwave signals is proposed and experimentally demonstrated. Temporal convolution involves three operations: time reversal of one microwave signal, the multiplication of the time-reversed signal with a second microwave signal, and the...
In addition, a sort of photonic-assisted RF scanning receivers based on simply tuning an optical carrier is also reported, which sweeps the entire frequency range with the discrete steps and then down-converts the RF signals [25], [26]. However, it requires measurement of the frequencies of...
Results Photonic-assisted microwave signal multiplication. Figure 1 illustrates the schematic illustration of the proposed photonic frequency-multiplicated microwave signal generation system using an integrated silicon MZM. Continuous-wave (CW) light from a tunable laser diode (TLD) is sent to the...
We propose and analyze a photonic-assisted periodic triangular-shaped pulses generator, in which a continuous wave (CW) laser is connected to a dual electrode Mach-Zehnder modulator (De-MZM), and then the De-MZM is connected with a normal dispersion fiber or element. A radio frequency (RF)...
A photonic-assisted instantaneous microwave frequency measurement (IFM) system is demonstrated with add-drop optical ring resonators (ORRs) on silicon-on-insulator (SOI) platform. By launching a double-sideband suppressed carrier modulated optical signal into the ring, a monotonous amplitude comparison ...

Here, we introduce photonic chip assisted CLEM, enabling multi-modal total internal reflection fluorescence (TIRF) microscopy over large field of view and high precision localization of the target area of interest within EM. The photonic chips are used as a substrate to hold, to illuminate and ...
We propose an optical dual-single-sideband (dual-SSB) modulated 16384-quadrature amplitude modulation (QAM) photonic vector millimeter-wave (mm-wave) signal generation scheme based on delta-sigma modulation (DSM). With the aid of the DSM, the severe nonlinear distortion of envelope detection for ...
Researchers have combined artificial intelligence and photonics technology to develop a robust new method for detecting counterfeit chips. The RAPTOR system illustrated here uses an attention mechanism for prioritizing nanoparticle correlations across pre-tamper and post-tamper samples before passing them ...
