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…
Impact of nonlinear spectral broadening on the phase noise properties of electro-optic frequency comb
Aleksandr Razumov, Yijia Cai, Jasper Riebesehl +5
Electro-optic modulation is an attractive approach for generating flat, stable, and low-noise optical frequency combs with relatively high power per comb line. However, a key limit…
Integrated recurrent optical spectral slicer for equalization of 100-km C-band IM/DD transmission
I. Teofilovic, K. Sozos, H. Liu +10
A silicon-photonics recurrent spectral filter is designed, fabricated, and system tested to pro-vide optical pre-processing in a 32-GBd PAM-4 C-band transmission. Performance below…
Experimental Analysis of a Self-Coherent M-QAM Receiver by Means of Recurrent Optical Spectrum Slicing and Direct Detection
Kostas Sozos, Francesco Da Ros, Senior Member Optica +6
High order modulation formats constitute the most prominent way for increasing spectral efficiency in transmission systems. Coherent transceivers that support such higher order for…
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…
