Abstract:Optical frequency combs (OFCs) have become increasingly pervasive in recent years, with their advantageous frequency coherence properties enabling significant developments in numerous fields, such as optical communications, spectroscopy, and microwave signal processing. Recent interest in OFC development emphasizes minimizing and mitigating phase noise of individual comb lines for high-quality signal generation, processing, and detection. Cavity-less electro-optic combs and parametric combs are attractive sour… Show more
We study the spacing tunability of an EO-comb-seeded parametric frequency comb generator with 90 nm bandwidth and 8-dB spectral flatness, demonstrating space tuning over 25 and 32 GHz with a maintained spectral profile.
