Splitting white light into its constituent spectral components has been of interest ever since Newton first discovered the phenomenon of color separation. Many devices have since been conceived to ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

The chameleon changes its color by adjusting the spacing between photonic crystals in its skin to modulate light reflection (Figure 1). A research team at the University of California at Berkeley has ...
