“…Experiments involving arrayed detectors where performed only after intensified CCD (iCCD) cameras became available, which provided sufficient detection efficiency of a few ten percent and temporal discrimination to perform correlation measurements. The latter was achieved by triggering the image intensifier with the detection signal from the bucket detector, images where obtained by integrating many intensifier frames in one CCD readout …”

Quantum imaging is a multifaceted field of research that promises highly efficient imaging in extreme spectral ranges as well as ultralow‐light microscopy. Since the first proof‐of‐concept experiments over 30 years ago, the field has evolved from highly fascinating academic research to the verge of demonstrating practical technological enhancements in imaging and microscopy. Here, the aim is to give researchers from outside the quantum optical community, in particular those applying imaging technology, an overview of several promising quantum imaging approaches and evaluate both the quantum benefit and the prospects for practical usage in the near future. Several use case scenarios are discussed and a careful analysis of related technology requirements and necessary developments toward practical and commercial application is provided.

One spatially incoherent beam propagates through an object and is collected by a detector, called “bucket detector” that has no spatial resolution (Figure ) .

In this perspective article, we review the optical study of different biophotonic geometries and biological structures using classical light in linear and nonlinear regime, especially highlighting the link between these morphologies and modern biomedical research. Additionally, the importance of nonlinear optical study in biological research, beyond traditional cell imaging is also highlighted and described. Finally, we present a short introduction regarding nonclassical light and describe the new future perspective of quantum optical study in biology, revealing the link between quantum realm and biological research.

Dynamic and multi‐dimensional manipulation of laser emission with light allows for optical coding, computing, and imaging photonic chips. However, the coupling balance between photonic resonance and transmission is a formidable challenge due to the uncontrollable chiral microcavity with photo‐reversibility, which is limited to the multi‐freedom of the laser with sustainable and repeatable output beams. Herein, a helical superstructure system with a unique intrinsic chiral photoswitch is developed for resolving the always pendent problems on organized defects in the microcavity. The unique intrinsic chirality based on the photoswitchable system allows laser emission with a sharp and narrow band‐width, with both remarkable thermodynamic stability and robust fatigue‐resistance. A quadri‐dimensional manipulable laser, featuring wavelength‐tunability, wavefront‐shaping, spin angular momentum (SAM), and orbital angular momentum (OAM), is successfully established with the assistance of the photoresponsive intrinsic chiral superstructure with photoreversibility. This technology marks an important milestone, and sketches a future framework for the realms of nanophotonic information encoding, security imprinting, and integrated photonics.
