Optical techniques are methods that use light to probe or control matter. One prominent example is optical spectroscopy, which includes such methods as pump–probe spectroscopy, Raman spectroscopy and photoemission spectroscopy. Other examples of optical techniques are microscopy, interferometry, ellipsometry, optical tweezers, and imaging and sensing.
Sub-cycle confinement and control of phase transitions in strongly correlated materials are theoretically demonstrated, potentially providing a way to investigate electron dynamics on timescales previously unattainable with these materials.
The buildup and operation of a custom single-molecule localization microscope with state-of-the-art performance and advanced features bridges the gap between entry-level open-source projects and costly commercial systems.
Yibo Dong et al. implement a compact and robust diffractive neural network chip with a virtually unlimited lifetime for optical inference. The chip demonstrates high accuracy and high stability even after high temperature aging, aiming at applications in extreme environments.
Precise and spatio-temporal control of crystallization kinetics is important but challenging. Here, the authors propose an optical strategy called optofluidic crystallithography to steer the growth of single-crystalline halide perovskites.

Ultrasound-induced luminescence in trianthracene derivative-based nanoparticles enables tumour imaging and immunological profiling in a variety of in vivo models.
A non-common-path interferometric scheme enables holographic detection of single proteins of mass 90 kDa and estimation of single-protein polarizability.
