Unveiling the origins of quasi-phase matching spectral imperfections in thin-film lithium niobate frequency doublers
Jie Zhao, Xiaoting Li, Ting-Chen Hu +10
Thin-film lithium niobate (TFLN) based frequency doublers have been widely recognized as essential components for both classical and quantum optical communications. Nonetheless, th…
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…
Impulse Response Characterization of a Commercial Multimode Fiber using Superconducting Nanowire Single-Photon Detectors
Yuanhang Zhang, Nicolas K. Fontaine, Mikael Mazur +4
Time-of-flight measurements are key to study distributed mode coupling and differential mode group delay (DMDG) in multimode fibers (MMFs). However, current approaches using regula…
Simultaneous Sorting of Wavelengths and Spatial Modes using Multi-Plane Light Conversion
Yuanhang Zhang, He Wen, Alireza Fardoost +5
We propose a wavelength-mode sorter realized by multi-plane light conversion (MPLC). For the first time, to our best knowledge, wavelengths and spatial modes can be sorted simultan…
Ultrabroadband Polarization Insensitive Hybrid using Multiplane Light Conversion
Nicolas K. Fontaine, Yuanhang Zhang, Haoshuo Chen +10
We designed, fabricated and tested an optical hybrid that supports an octave of bandwidth (900-1800 nm) and below 4-dB insertion loss using multiplane light conversion. Measured ph…
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…
Integrated cladding-pumped multi-core, few-mode erbium-doped fibre amplifier for space-division multiplexed communications
H. Chen, C. Jin, B. Huang +9
Space-division multiplexing (SDM), whereby multiple spatial channels in multimode and multicore optical fibers are used to increase the total transmission capacity per fiber, is be…
