A novel ultra-black broadband absorber concept based on a needle-like silicon nanostructure has been developed by Jena researchers.
A new approach to control light with light without the need for optical nonlinearity has been suggested by a Russian-British research group.
Coherent anti-Stokes Raman scattering microscopy offers noninvasive label-free imaging, high sensitivity, and chemical specificity.
Multimodal nonlinear microscopy has matured to a key imaging modality in life science and biomedicine.
IR and Raman spectral imaging can distinguish between tissue types, disease types and stages, and even identify the primary tumors from spectral patterns observed in metastatic cells.
Optical tweezers are standard today. Recently, more sophisticated trapping configurations have been realized based on holographic beam shaping techniques.
Blue laser diodes operated in stimulated emission offer a potential alternative to traditional solid-state lighting based on light-emitting diodes.
A new compact sensor system based on an LED pumped polymer laser detects explosive vapors quickly and sensitively.
Mapping of chemical contents and their spatial distribution in a complex biological environment such as cells can be achieved by a new imaging modality.
