Simultaneous transmission of hyper-entanglement in 3 degrees of freedom through a multicore fiber
Lukas Achatz, Lukas Bulla, Evelyn A. Ortega +5
Entanglement distribution is at the heart of most quantum communication protocols. Inevitable loss of photons along quantum channels is a major obstacle for distributing entangled…
Alignment of Free-Space Coupling of Few-Mode Fibre to Multi-Mode Fibre using Digital Holography
Menno van den Hout, Sjoerd van der Heide, Thomas Bradley +11
Off-axis digital holography is used to align a few-mode fiber to a multi-mode fiber in a free-space optical setup. Alignment based on power coupling measurements alone cannot guara…
Optical Field Characterization using Off-axis Digital Holography
Sjoerd van der Heide, Bram van Esch, Menno van den Hout +10
Angular resolved digital holography is presented as a technique for real-time characterization of the full optical field (amplitude and phase) of space-division multiplexing compon…
Demonstration of high-efficiency photonic lantern couplers for PolyOculus
Christina D. Moraitis, Juan Carlos Alvarado-Zacarias, Rodrigo Amezcua-Correa +2
The PolyOculus technology produces large-area-equivalent telescopes by using fiber optics to link modules of multiple semi-autonomous, small, inexpensive, commercial-off-the-shelf…
Experimental space-division multiplexed polarization-entanglement distribution through 12 paths of a multicore fiber
Evelyn A. Ortega, Krishna Dovzhik, Jorge Fuenzalida +6
The development and wide application of quantum technologies highly depend on the capacity of the communication channels distributing entanglement. Space-division multiplexing (SDM…
1 Tbit/s/ Transmission Over a 130 km Link Consisting of Graded-Index 50 m Core Multi-Mode Fiber and 6LP Few-Mode Fiber
Menno van den Hout, Sjoerd van der Heide, John van Weerdenburg +7
We demonstrate 1 Tbit/s/ single-span transmission over a heterogeneous link consisting of graded-index 50 m core multi-mode fiber and 6LP few-mode fiber using a Kramers-Kroni…
Experimental validation of MDL emulation and estimation techniques for SDM transmission systems
Menno van den Hout, Ruby S. B. Ospina, Sjoerd van der Heide +8
We experimentally validate a mode-dependent loss (MDL) estimation technique employing acorrection factor to remove the MDL estimation dependence on the SNR when using a minimum mea…
Exploiting Angular Multiplexing for Polarization-diversity in Off-axis Digital Holography
Sjoerd van der Heide, Rutger van Anrooij, Menno van den Hout +9
Digital holography measures the complex optical field and transfer matrix of a device, polarization-diversity is often achieved through spatial multiplexing. We introduce angular m…
Mode-dependent Loss and Gain Estimation in SDM Transmission Based on MMSE Equalizers
Ruby S. B. Ospina, Menno van den Hout, Juan Carlos Alvarado-Zacarias +7
The capacity in space division multiplexing (SDM) systems with coupled channels is fundamentally limited by mode-dependent loss (MDL) and mode-dependent gain (MDG) generated in com…
Mode-Multiplexed Full-Field Reconstruction Using Direct and Phase Retrieval Detection
Haoshuo Chen, Juan Carlos Alvarado-Zacarias, Hanzi Huang +4
We realize mode-multiplexed full-field reconstruction over six spatial and polarization modes after 30-km multimode fiber transmission using intensity-only measurements without any…
First Transmission of a 12D Format Across 3 Coupled Spatial Modes of a 3-Core Coupled-Core Fiber at a Spectral Efficiency of 4 bits/s/Hz
René-Jean Essiambre, Roland Ryf, Sjoerd van der Heide +10
We demonstrate the first transmission of a new twelve-dimensional modulation format over a three-core coupled-core multicore fiber. The format occupies a single time slot spread ac…
Time reversed optical waves by arbitrary vector spatiotemporal field generation
Mickael Mounaix, Nicolas K. Fontaine, David T. Neilson +4
Lossless linear wave propagation is symmetric in time, a principle which can be used to create time reversed waves. Such waves are special 'pre-scattered' spatiotemporal fields, wh…
White Gaussian Noise Based Capacity Estimate and Characterization of Fiber-Optic Links
Roland Ryf, John van Weerdenburg, Roberto A. Alvarez-Aguirre +7
We use white Gaussian noise as a test signal for single-mode and multimode transmission links and estimate the link capacity based on a calculation of mutual information. We also e…
