Abstract

Abstract

We demonstrate the first sub-GHz flat-top RFphotonic
filter based on a wide-band 25 GHz-pitched
parametric comb. A narrow filter was constructed by fourth
order dispersion compensation of the fiber for the first time. The
filter performance was tested by digital modulated RF data
retrieval.

TuD3.2 - TIME-MAPPED SPECTROGRAM ANALYSIS WITH RELAXED DETECTION SAMPLING RATE

Abstract

Abstract

We propose an approach for relaxing the detection sampling rate in time-mapped spectrogram analysis. Output spectrograms are fully recovered by sampling at nearly the Nyquist bandwidth of the waveform under analysis, relaxing the needed detection sampling rate by at least one order of magnitude.

TuD3.3 - DIRECT OPTICAL LINK BETWEEN A MMWAVE OPTICAL FREQUENCY COMB AND A CHIP-SCALE MODE-LOCKED LASER

Abstract

Abstract

A 10GHz MLL-PIC is synchronized to an optical frequency comb at 120GHz using harmonic injection locking. After injection, the Allan Deviation in the repetition rate of the MLL-PIC is 10-11 at 1s. The mmWave comb features an intracavity high-finesse etalon to enhance its frequency stability.

Abstract

Abstract

We demonstrate recovery of Mackey-Glass waveforms and multi-frequency sinusoids using speckle-based reservoir computer. Neurons and RF waveforms drive a spatial light modulator imaged onto a multimode fiber. Fiber output is imaged onto a camera, digitally processed and fed back into the fiber through the modulator.

TuD3.5 - INTEGRATED MICROWAVE PHOTONICS: THE PATH TO HIGH QUALITY MILLIMETER AND TERAHERTZ WAVE SIGNAL GENERATION?

Abstract

Abstract

Microwave photonics allowed reaching the millimeter (30-300 GHz) and Terahertz (300-3000 GHz) ranges. For wide frequency tuning, optical heterodyne is the most common approach at the cost of frequency drift and phase noise. This talk addresses the advantages of photonic integration to improve signal quality.
