Subspace tracking: a novel measurement method to test the standard phase noise model of optical frequency combs
Darko Zibar, Holger Heebøll, Jasper Riebesehl +3
The introduction of digital signal processing (DSP) assisted coherent detection has been a cornerstone of modern fiber-optic communication systems. The ability to digitally, i.e. a…
Resonant EO combs: Beyond the standard phase noise model of frequency combs
Holger R. Heebøll, Pooja Sekhar, Jasper Riebesehl +6
A resonant electro-optic (EO) frequency comb is generated through electro-optic modulation of laser light within an optical resonator. Compared to cavity-less EO combs generated in…
Phase Noise Characterization of Cr:ZnS Frequency Comb using Subspace Tracking
Aleksandr Razumov, Sergey Vasilyev, Mike Mirov +4
We present a comprehensive phase noise characterization of a mid-IR Cr:ZnS frequency comb. Despite their emergence as a platform for high-resolution dual-comb spectroscopy, detaile…
Digital Signal Processing Techniques for Noise Characterization of Lasers and Optical Frequency Combs: A Tutorial
Jasper Riebesehl, Holger R. Heebøll, Aleksandr Razumov +2
Performing noise characterizations of lasers and optical frequency combs on sampled data offers numerous advantages compared to analog measurement techniques. One of the main advan…
