Experimental End-to-End Optimization of Directly Modulated Laser-based IM/DD Transmission
Sergio Hernandez, Christophe Peucheret, Francesco Da Ros +1
Directly modulated lasers (DMLs) are an attractive technology for short-reach intensity modulation and direct detection communication systems. However, their complex nonlinear dyna…
Quantum Noise Limited Temperature-Change Estimation for Phase-OTDR Employing Coherent Detection
Huwei Wang, Roman Ermakov, Francesco Da Ros +1
The quantum limit is a fundamental lower bound on the uncertainty when estimating a parameter in a system dominated by the minimum amount of noise (quantum noise). For the first ti…
Low-Complexity Event Detection and Identification in Coherent Correlation OTDR Measurements
Jasper Müller, Ognjen Jovanovic, Florian Azendorf +7
Pairing coherent correlation OTDR with low-complexity analysis methods, we investigate the detection of fast temperature changes and vibrations in optical fibers. A localization ac…
End-to-End Learning of Transmitter and Receiver Filters in Bandwidth Limited Fiber Optic Communication Systems
Søren Føns Nielsen, Francesco Da Ros, Mikkel N. Schmidt +1
This paper investigates the application of end-to-end (E2E) learning for joint optimization of pulse-shaper and receiver filter to reduce intersymbol interference (ISI) in bandwidt…
Experimental Demonstration of End-to-End Optimization for Directly Modulated Laser-based IM/DD Systems
Sergio Hernandez, Christophe Peucheret, Francesco Da Ros +1
We experimentally demonstrate the joint optimization of transmitter and receiver parameters in directly modulated laser systems, showing superior performance compared to nonlinear…
Blind Equalization using a Variational Autoencoder with Second Order Volterra Channel Model
Søren Føns Nielsen, Darko Zibar, Mikkel N. Schmidt
Existing communication hardware is being exerted to its limits to accommodate for the ever increasing internet usage globally. This leads to non-linear distortion in the communicat…
