Second-harmonic generation from metallodielectric multilayer photonic-band-gap structures

Photonic band-gap structures

The analogy between electromagnetic wave propagation in multidimensionally periodic structures and electronwave propagation in real crystals has proven to be a fruitful one. Initial efforts were motivated by the prospect of a photonic band gap, a frequency band in three-dimensional dielectric structures in which electromagnetic waves are forbidden irrespective of the propagation direction in sp...

Transparent photonic band in metallodielectric nanostructures

Under certain conditions, a transparent photonic band can be designed into a one-dimensional metallodielectric nanofilm structure. Unlike conventional pass bands in photonic crystals, where the finite thickness of the structure affects the transmission of electromagnetic fields having frequency within the pass band, the properties of the transparent band are almost unaffected by the finite thic...

Tunable-wavelength second harmonic generation from GaP photonic crystal cavities coupled to fiber tapers.

We demonstrate up to 30 nm tuning of gallium phosphide photonic crystal cavities resonances at aproximately 1.5 microm using a tapered optical fiber. The tuning is achieved through a combination of near-field perturbations and mechanical deformation of the membrane, both induced by the fiber probe. By exploiting this effect, we show fiber-coupled second harmonic generation with a tuning range o...

Photonic band gaps of AB3 and B3 structures of metallodielectric spheres

Using the vector-wave multiple-scattering method we have calculated the photonic band structures of AB3 and B3 crystals composed of perfect metal spheres in air. It is shown that AB3 photonic crystal contains a large photonic band gap and B3 photonic crystal has more than one gap when the filling ratio of metal spheres exceeds a threshold. The multiple photonic gaps of the B3 structure are usef...
