On-chip sampling of optical fields with attosecond resolution

Nature Photonics, Published online: 15 April 2021; doi:10.1038/s41566-021-00792-0An on-chip, sub-optical-cycle sampling technique for measuring arbitrary electric fields of few-femtojoule near-infrared optical pulses in ambient conditions is demonstrated, offering an improvement of roughly six orders of magnitude in energy sensitivity compared with...

Large-scale neuromorphic optoelectronic computing with a reconfigurable diffractive processing unit

Nature Photonics, Published online: 12 April 2021; doi:10.1038/s41566-021-00796-wLinear diffractive structures are by themselves passive systems but researchers here exploit the non-linearity of a photodetector to realize a reconfigurable diffractive ‘processing’ unit. High-speed image and video recognition is demonstrated.

Scattering invariant modes of light in complex media

Nature Photonics, Published online: 08 April 2021; doi:10.1038/s41566-021-00789-9The concept of scattering invariant modes is introduced to produce the same transmitted field profiles through a multiple scattering sample and a reference medium. Their correlations with the ballistic light can be used to improve imaging inside scattering materials.

Room-temperature electron spin polarization exceeding 90% in an opto-spintronic semiconductor nanostructure via remote spin filtering

Nature Photonics, Published online: 08 April 2021; doi:10.1038/s41566-021-00786-yAn electron spin polarization of 90% is achieved in a non-magnetic nanostructure at room temperature without magnetic field. This is accomplished by remote spin filtering of InAs quantum-dot electrons via an adjacent tunnelling-coupled GaNAs spin filter.
