Transmission Filter

A design of multichannel transmission filter at microwave is proposed. It is based on the use of the finite plasma photonic crystal operating at frequency below the plasma frequency. We consider a design structures of (AB)qA, where A is the dielectric material, B is the plasma layer, and q is the number of periods. It is found that the number of channels is equal to q-1. We show that the locations such multiple channels are in the pass band of the infinite plasma-dielectric photonic crystal. The idea of such design is thus to engineer the photonic pass band, which is fundamentally different from the usual design by engineering the photonic stop band like the multilayer Fabry-Perot transmission filter. The physical mechanism of multiple channels is also discussed.

The Impact

In addition to the most common applications of macroporous film: Supplying a large surface area, PC-FTO (macroporous fluorine-doped tin oxide with photonic crystal structure) can be employed as a template to control the morphologies of WO3 for exposing a more active facet, and enhance the overall photo-electron conversion efficiency for the embedded photoactive materials under changing illumination incidence through refracting and scattering. The optical features of PC-FTO film was demonstrated by DRUVS (diffuse reflectance UV-vis spectra). Plate-like WO3 were directly synthesized inside the PC-FTO film as a control group photoanode, Ag2S quantum dots were subsequently decorated on WO3 to tune the light absorption range. The impact of photonic crystal film on the photoactivity of Ag2S/WO3 was demonstrated by using the photoelectrochemical current density as a function of the incidence of the simulated light source.

Assembly Technique

Inverse opal photonic crystals of Eu3+ doped LaPO4 (LaPO4: Eu）were prepared by a self-assembly technique in combination with a sol-gel method. In the preparation process, Eu3+ doped LaPO4 precursors were filled into the interstices of the opal template assembled by monodispersive polystyrene microspheres. The polystyrene template was then removed by calcination at 650 °C for 5h, meanwhile, Eu3+doped LaPO4 inverse opal photonic crystal was formed. The photoluminescence (PL) from Eu3+ doped LaPO4 inverse opal photonic crystal was studied. The effect of the photonic stop-band on the spontaneous emission of Eu3+ has been observed in the inverse opal photonic crystals of Eu3+ doped LaPO4. Significant suppression of the emission was detected if the photonic band-gap overlaps with the Eu3+ ions emission band.
