A high-level schematic of the photonic integrated chip, developed by the Gaeta lab, for all-optical optical frequency division, or OFD – a method of converting a high-frequency signal to a lower ...

Frequency multipliers are essential to generate a high frequency, low phase-noise signal from a low frequency, high performance oscillator. Figure 1 shows a phase noise comparison between a signal ...

The Photonics Research Group and IDlab, two imec research groups at Ghent University, and imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, have published ...

How a single silicon chip was designed to be microwave and optical signal-processing engine. The various roles for which this engine can be reconfigured. The performance considerations that were ...
