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…
Extended Kalman Smoothing of Free Spin Precession Signals for Accurate Magnetic Field Determination
Jasper Riebesehl, Lutz Mertenskötter, Wiebke Pohlandt +2
We present a novel application of the Extended Kalman Smoother (EKS) for highly accurate frequency estimation from free spin precession signals of polarized He. Traditional app…
Fiber-coupled external cavity DFB-laser
David C. Nak, Jasper Riebesehl, Andreas Hemmerich
Narrow-linewidth, compact and robust laser systems are of high interest, especially with prospects for portable quantum metrological applications. We realized an external cavity DF…
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…
