Programmable spatiotemporal OAM optical toroidal beams with completely tunable properties
Andrew V. Komonen, Nicolas K. Fontaine, Martin Plöschner +4
Spatiotemporal toroidal orbital angular momentum (OAM) beams are a developing class of spatiotemporal beams which have key applications within quantum physics, metrology, imaging a…
Frequency Comb-based Wavelength Division Multiplexing and Detection without Wavelength Demultiplexers
Di Che, Zhongdi Peng, Mikael Mazur +1
We demonstrate a wavelength division multiplexing (WDM) concept using demultiplexer-free frequency combs at both transmitter and receiver in a 4-wavelength 200-GHz-grid WDM system…
Enabling a multifunctional telecommunications fiber optic network: Ultrastable optical frequency transfer and attosecond timing in deployed multicore fiber
Nazanin Hoghooghi, Mikael Mazur, Nicolas Fontaine +10
The telecommunications industry's deployment of billions of kilometers of optical fiber has created a vast global network that can be exploited for additional applications such as…
2.4-THz Bandwidth Optical Coherent Receiver Based on a Photonic Crystal Microcomb
Callum Deakin, Jizhao Zang, Xi Chen +5
We demonstrate a spectrally-sliced single-polarization optical coherent receiver with a record 2.4-THz bandwidth, using a 200-GHz tantalum pentoxide photonic crystal microring reso…
Multi-Plane Light Conversion: A Practical Tutorial
Yuanhang Zhang, Nicolas K. Fontaine
Multi-plane light conversion (MPLC) has recently been developed as a versatile tool for manipulating spatial distributions of the optical field through repeated phase modulations.…
Roadmap on spatiotemporal light fields
Yijie Shen, Qiwen Zhan, Logan G. Wright +42
Spatiotemporal sculpturing of light pulse with ultimately sophisticated structures represents the holy grail of the human everlasting pursue of ultrafast information transmission a…
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…
