Phase conjugation with spatially incoherent light in complex media
Sha** light deep inside complex media such as biological tissue is critical to many research fields. Although the coherent control of scattered light via wavefront sha** has led to substantial advances in ...

Imaging and computing with disorder
Complex and inhomogeneous media are ubiquitous around us. Snow, fog, biological tissues and turbid water — even just a piece of frosted glass — are opaque to light due to scattering. Similarly, radio waves bou...

Roadmap on chaos-inspired imaging technologies (CI2-Tech)
In recent years, rapid developments in imaging concepts and computational methods have given rise to a new generation of imaging technologies based on chaos. These chaos-inspired imaging technologies (CI2-Tech) c...

Open AccessMean path length invariance in wave-scattering beyond the diffusive regime
Diffusive random walks feature the surprising property that the average length of all possible random trajectories that enter and exit a finite domain is determined solely by the domain boundary. Changes in th...

Readout of fluorescence functional signals through highly scattering tissue
Fluorescence is a powerful means to probe information processing in the mammalian brain1. However, neuronal tissues are highly heterogeneous and thus opaque to light. A wide set of non-invasive or invasive techni...

Programmable linear quantum networks with a multimode fibre
Reconfigurable quantum circuits are fundamental building blocks for the implementation of scalable quantum technologies. Their implementation has been pursued in linear optics through the engineering of sophis...

Non-invasive single-shot imaging through scattering layers and around corners via speckle correlations
Optical imaging through and inside complex samples is a difficult challenge with important applications in many fields. The fundamental problem is that inhomogeneous samples such as biological tissue randomly ...

Adaptive pum** for spectral control of random lasers
Random lasers generate the optical feedback required for stimulated emission by scattering light from disordered particles. Their inherent randomness, however, makes controlling the emission wavelength difficu...

Demonstration of an ultracold micro-optomechanical oscillator in a cryogenic cavity
Cooling optomechanical resonators to their quantum-mechanical ground state could enable the observation of quantum effects in macroscopic objects. The experimental cooling of a 43-ng silicon-nitride beam to a ...
