    Plasmonic-Photonic Crystals Studied to Further Sensor, Laser Research

    Article obtained from Photonics RSS Feed.

    As part of their research into optical states of plasmonic-photonic crystals (PPCs), scientists at Kazan Federal University investigated three-dimensional opal-like plasmonic-photonic crystals (OLPPCs), focusing on why OLPPCs do not admit light of certain wavelengths. (This is called the photonic bandgap — it is the range of light wavelengths where propagation through a crystal is difficult).

    The primary conditions for passing a light beam with the wavelength of the photonic bandgap and a certain polarization through an OLPPC are the continuity of the gold layer, with a…
