The combination of a plasmonic color filter and a terahertz metamaterial absorber exhibits unique resonant phenomena over several decades of wavelengths.
Due to their unique properties these fascinating materials are predicted to possess a complete photonic bandgap without any long-range order.
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.
Proposed design uses an external source of energy to significantly broaden its bandwidth of operation.
