Sensitivity Limits for -OTDR
Juan M. Marin, Roman Ermakov, Huwei Wang +2
We demonstrate a new lower bound on the sensitivity of -OTDR by estimating phase using Kalman filtering. Numerical analysis shows a 35-dB reduction in the minimum detectab…
Mapping Source-Resolved Phase-Noise Transfer in Soliton Microcombs
Zhongan Zhao, Aleksandr Razumov, Viswanathan Sankar +2
Phase noise limits the coherence and stability of soliton microcombs, yet its origin is difficult to trace because multiple noise sources act simultaneously. It is often represente…
Machine Learning based Optimization of CV-QKD Under Practical Constraints
Svitlana Matsenko, Amirhossein Ghazisaeidi, Marcin Jarzyna +4
Practical hardware limitations, including finite transmitter and receiver filter lengths as well as the finite resolution of digital-to-analog and analog-to-digital converters, lea…
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…
Interference Fringe Mitigation in Short-Delay Self-Heterodyne Laser Phase Noise Measurements
Jasper Riebesehl, David C. Nak, Darko Zibar
Self-heterodyne techniques are widely used for laser phase noise characterization due to their simple experimental setup and the removed need for a reference laser. However, when i…
Mode Mismatch Mitigation in Gaussian-Modulated CV-QKD
Svitlana Matsenko, Amirhossein Ghazisaeidi, Marcin Jarzyna +4
Technical limitations in pulse shaping lead to mode mismatch, which significantly reduces the secure key rate in CV-QKD systems. To address this, a machine learning approach is emp…
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…
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…
