Extraction of Bend-Resolved Modal Basis in Deformed Multimode Fiber
Lubomir Skvarenina, Stephen Simpson, Yashar Alizadeh +1
Mode mixing in optical fibers caused by mechanical bending induces perturbations that distort the spatial field profile of coherent beams as they propagate through few-mode or mult…
Ultrafast 4D scanning transmission electron microscopy for imaging of localized optical fields
Petr Koutenský, Neli Laštovičková Streshkova, Kamila Moriová +4
Ultrafast electron microscopy aims for imaging transient phenomena occurring on nanoscale. One of its goals is to visualize localized optical and plasmonic modes generated by coher…
Observations of a PT-like phase transition and limit cycle oscillations in non-reciprocally coupled optomechanical oscillators levitated in vacuum
Vojtěch Liška, Tereza Zemánková, Petr Jákl +4
Nanoparticles levitated in an optical trap provide a versatile platform to study mechanical oscillators in a controlled environment with tuneable parameters. Recently, it has becom…
Controlling light propagation in multimode fibers for imaging, spectroscopy and beyond
Hui Cao, Tomáš Čižmár, Sergey Turtaev +2
Light transport in a highly multimode fiber exhibits complex behavior in space, time, frequency and polarization, especially in the presence of mode coupling. The newly developed t…
All-optical sub-Kelvin sympathetic cooling of a levitated microsphere in vacuum
Yoshihiko Arita, Graham D. Bruce, Ewan M. Wright +3
We demonstrate all-optical sympathetic cooling of a laser-trapped microsphere to sub-Kelvin temperatures, mediate by optical binding to a feedback-cooled adjacent particle. Our stu…
Absolute frequencies of H13C14N hydrogen cyanide transitions in 1,5 μm region with saturated spectroscopy and sub-kHz scanning laser
Jan Hrabina, Martin Hosek, Simon Rerucha +5
The wide span and high density of lines in its rovibrational spectrum render hydrogen cyanide a useful spectroscopic media for referencing absolute frequencies of lasers in optical…
How to build the optical inverse of a multimode fibre
Unė G. Būtaitė, Hlib Kupianskyi, Tomáš Čižmár +1
When light propagates through a multimode optical fibre (MMF), the spatial information it carries is scrambled. Wavefront shaping can undo this scrambling, typically one spatial mo…
Roadmap on Wavefront Shaping and deep imaging in complex media
Sylvain Gigan, Ori Katz, Hilton B. de Aguiar +42
The last decade has seen the development of a wide set of tools, such as wavefront shaping, computational or fundamental methods, that allow to understand and control light propaga…
Time of flight 3D imaging through multimode optical fibres
Daan Stellinga, David B. Phillips, Simon Peter Mekhail +4
Time-of-flight (ToF) 3D imaging has a wealth of applications, from industrial inspection to movement tracking and gesture recognition. Depth information is recovered by measuring t…
All-optical manipulation of photonic membranes
Meisam Askari, Blair C. Kirkpatrick, Tomas Čižmár +1
Here we demonstrate the all-optical manipulation of polymeric membranes in microfluidic environments. The membranes are decorated with handles for their use in holographic optical…
Observing distant objects with a multimode fibre-based holographic endoscope
Ivo T. Leite, Sergey Turtaev, Dirk E. Boonzajer Flaes +1
Holographic wavefront manipulation enables converting hair-thin multimode optical fibres into minimally invasive lensless imaging instruments conveying much higher information dens…
Compressively sampling the optical transmission matrix of a multimode fibre
Shuhui Li, Charles Saunders, Daniel J. Lum +4
Measurement of the optical transmission matrix (TM) of an opaque material is an advanced form of space-variant aberration correction. Beyond imaging, TM-based methods are emerging…
Memory effect assisted imaging through multimode optical fibres
Shuhui Li, Simon A. R. Horsley, Tomas Tyc +2
When light propagates through opaque material, the spatial information it holds becomes scrambled, but not necessarily lost. Two classes of techniques have emerged to recover this…
Investigating the use of the hydrogen cyanide (HCN) as an absorption media for laser spectroscopy
Martin Hosek, Simon Rerucha, Lenka Pravdova +4
The laser spectroscopy is a fundamental approach for the realisation of traceable optical frequency standards. In the m wavelength band, widely used in telecommunications,…
Laser source for dimensional metrology: investigation of an iodine stabilized system based on narrow linewidth 633 nm DBR diode
Simon Rerucha, Andrew Yacoot, Tuan M Pham +4
We demonstrated that an iodine stabilized Distributed Bragg Reflector (DBR) diode based laser system lasing at a wavelength in close proximity to nm could be used as an a…
Tunable soft-matter optofluidic waveguides assembled by light
Oto Brzobohaty, Lukas Chvatal, Alexandr Jonas +4
Development of artificial materials exhibiting unusual optical properties is one of the major strands of current photonics research. Of particular interest are soft-matter systems…
