Mode-selective photonic lanterns for space-division multiplexing
Sergio G. Leon-Saval,Nicolas K. Fontaine,Joel R. Salazar-Gil,Burcu Ercan,Roland Ryf,Joss Bland-Hawthorn +5 more
TL;DR: A 3x1 fiber-based photonic lantern spatial-multiplexer with mode-selectivity greater than 6 dB and transmission loss of less than 0.3 dB is demonstrated, which are to the authors' knowledge the lowest insertion and mode-dependent loss devices.
Journal ArticleDOI
Laguerre-Gaussian mode sorter.
TL;DR: In this paper, the authors present a multi-plane light conversion scheme for large number of spatial modes in a scalable fashion, where the number of phase plates required scales with the dimensionality of the transformation.
Journal ArticleDOI
Demonstration of free space coherent optical communication using integrated silicon photonic orbital angular momentum devices
Tiehui Su,Ryan P. Scott,Stevan S. Djordjevic,Nicolas K. Fontaine,David J. Geisler,Xinran Cai,S. J. B. Yoo +6 more
TL;DR: Silicon photonic integrated circuits for free-space spatial-division-multiplexing (SDM) optical transmission with multiplexed orbital angular momentum (OAM) states over a topological charge range of -2 to +2.
Journal ArticleDOI
Geometric requirements for photonic lanterns in space division multiplexing.
TL;DR: This work uses modal analysis, the beam propagation method, and a transfer matrix technique to analyze the lanterns throughput along with its mode dependent loss and shows that unitary coupling between single-mode fibers and a multi-mode fiber is only possible by optimizing the arrangements of the cores.
Journal ArticleDOI
Survey of Photonic Switching Architectures and Technologies In Support Of Spatially and Spectrally Flexible Optical Networking {[}Invited]
Dan M. Marom,Paul D. Colbourne,Antonio D'Errico,Nicolas K. Fontaine,Yuichiro Ikuma,Roberto Proietti,Liangjia Zong,Jose Manuel Rivas-Moscoso,Ioannis Tomkos +8 more
TL;DR: This tutorial paper surveys the photonic switching hardware solutions in support of evolving optical networking solutions enabling capacity expansion based on the proposed approaches and presents the first cost comparisons, to the knowledge, of the different approaches in an effort to quantify such tradeoffs.
