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…
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…
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…
