Owing to reduced light scattering and tissue autofluorescence, in vivo fluorescence imaging
in the 1,000–3,000-nm near-infrared II (NIR-II) spectral range can afford non-invasive …

At the core of quantum photonic information processing and sensing, two major building
pillars are single-photon emitters and single-photon detectors. In this review, we …

The last decade has seen the development of a wide set of tools, such as wavefront
shaping, computational or fundamental methods, that allow us to understand and control …

The detection of individual quanta of light is important for quantum communication,
fluorescence lifetime imaging, remote sensing and more. Due to their high detection …

Photon excitation and emission at the NIR‐II spectral window enable high‐contrast deep‐
tissue bioimaging. However, multiplexed imaging with NIR‐II excitation and emission has …

Fluorophores emitting in the NIR-IIb wavelength range (1.5–1.7 μm) show great potential for
bioimaging due to their large tissue penetration. However, current fluorophores suffer from …

Intravital luminescence imaging in the second near-infrared window (NIR-II) enables
noninvasive deep-tissue imaging with high spatiotemporal resolution of live mammals …

Lidar has already achieved long-distance and high-accuracy detection due to the improved
sensitivity and timing accuracy of single-photon detectors (SPDs). However, single-photon …

Optical microscopy has enabled in vivo monitoring of brain structures and functions with
high spatial resolution. However, the strong optical scattering in turbid brain tissue and skull …

Multiphoton microscopy (MPM) is an enabling technology for visualizing deep-brain
structures at high spatial resolution in vivo. Within the low tissue absorption window, shifting …
