EH Modelling and Achievable Rate for FSO SWIPT Systems with Non-linear Photovoltaic Receivers
Nikita Shanin, Hedieh Ajam, Vasilis K. Papanikolaou +3
In this paper, we study optical simultaneous wireless information and power transfer (SWIPT) systems, where a photovoltaic optical receiver (RX) is illuminated by ambient light and…
Silicon Photonics Wavelength-Independent C-Band Tunable Optical Filter With Feasible Thermal Tuning Requirements
Saif Alnairat, Benjamin Wohlfeil, Stevan Djordjevic +1
A filter design based on Vernier microrings and wideband directional couplers is proposed for ASE noise suppression in next generation DCI applications. We demonstrate a 40 nm FSR-…
Distributed Sensing of Single Mode Fibers with Correlation Techniques
Florian Azendorf, André Sandmann, Michael Eiselt +1
In this paper, we report on the development progress of correlation-based optical time domain reflectometry (OTDR). Substituting the direct detection receiver with a coherent recei…
Hollow-core fiber Characterization with Correlation-Optical Time Domain Reflectometry
Florian Azendorf, Bernhard Schmauss, Bo Shi +3
Using a Correlation-OTDR, we characterized the temperature-induced group delay variations of two nested antiresonant nodeless hollow core fibers. The temperature sensitivity of bot…
Modeling and Design of IRS-Assisted Multi-Link FSO Systems
Hedieh Ajam, Marzieh Najafi, Vahid Jamali +2
In this paper, we investigate the modeling and design of intelligent reflecting surface (IRS)-assisted optical communication systems which are deployed to relax the line-of-sight (…
Intelligent Reflecting Surface-assisted Free-space Optical Communications
Vahid Jamali, Hedieh Ajam, Marzieh Najafi +3
Free-space optical (FSO) systems are able to offer the high data-rate, secure, and cost-efficient communication links required for applications such as wireless front- and backhaul…
Position Measurement of Multiple Microparticles in Hollow-Core Photonic Crystal Fiber by Coherent Optical Frequency Domain Reflectometry
Jasper Podschus, Max Koeppel, Bernhard Schmauss +4
Flying particle sensors in hollow-core photonic crystal fibers require accurate localization of the optically trapped microparticles. We report position measurement to micrometer-r…
Fiber as a temperature sensor with portable Correlation-OTDR as interrogator
Florian Azendorf, Annika Dochhan, Florian Spinty +3
In this paper, we report on the integration of a Correlation-OTDR into a portable unit (30 cm x 30 cm), based on a multi-processor system on chip (MPSoC) and a small formfactor plu…
Latency Measurement of 100 km Fiber Using Correlation-OTDR
Florian Azendorf, Annika Dochhan, Bernhard Schmauss +1
By means of C-OTDR (Correlation - Optical Time Domain Reflectometry), we measured the latency of100 km fiber with an accuracy of a few picoseconds. Based on iterating 49 measuremen…
Group Delay Measurements of Multicore Fibers with Correlation Optical Time Domain Reflectometry
Florian Azendorf, Annika Dochhan, Florian Spinty +3
Several multi-core fibers (MCF) were characterized using Correlation Optical Time Domain Reflectometry (C-OTDR) in terms of propagation delay and polarization mode dispersion (PMD)…
Characterization of Multi-Core Fiber Group Delay with Correlation OTDR and Modulation Phase Shift Methods
Florian Azendorf, Annika Dochhan, Krzysztof Wilczyński +8
Using a Correlation-OTDR and a modulation phase shift method we characterized four multi-core fibers. The results show that the differential delay depends on the position of the co…
Improvement of accuracy for measurement of 100-km fibre latency with Correlation OTDR
Florian Azendorf, Annika Dochhan, Jim Zou +2
We measured the latency of a 100 km fibre link using a Correlation OTDR. Improvements over previous results were achieved by increasing the probe signal rate to 10 Gbit/s, using di…
