1. A transparent metal photonic band gap device, comprising:

  • a first metal layer having a first metal thickness;

    a first interstitial layer having a first interstitial thickness formed on said first metal layer;

    a second metal layer having a second metal thickness formed on said first interstitial layer;

    a second interstitial layer having a second interstitial thickness formed on said second metal layer;

    a third metal layer having a third metal thickness formed on said second interstitial layer, wherein said thicknesses of said metal and interstitial layers are selected to form a photonic band gap structure having a transmission resonance range on at least one side of a photonic band gap range, the photonic band gap structure permitting transmission of light at wavelengths in a first wavelength range within the transmission resonance range and suppressing transmission of light at wavelengths in a second wavelength range within the photonic band gap range.
