The presentation will be in English / La présentation sera en anglais. 


Microwave photonics (MWP) is a typical optical signal processing application for optical communications, antenna systems, and 5G/6G networks. At the same time, optical frequency combs (OFC) and programmable optical filters enable this system to be reconfigurable. There are several approaches to creating OFC lines, such as the micro-ring resonator, cascaded electro-optic modulator, and mode-locked laser (MLL), in which the quantum dash (QDash) MLL is an ideal on-chip OFC source to provide low relative intensity noise (RIN), narrow linewidth, and flat comb spectrum.

In this seminar, we will present three typical applications of MWP systems using QDash MLL as the OFC source. The photonic beamforming illustrates a phased antenna array system that can do directional radiation and scanning. The MWP filter is a reconfigurable finite impulse response (FIR) filter, and a specially designed MWP filter can also be used for instantaneous frequency measurement.

In partnership with the High Throughput and Secure Networks (HTSN) Challenge program at National Research Council (NRC), we invite you to join this virtual seminar series to promote scientific information sharing, discussions, and interactions between researchers.
