Photochemically tunable photonic band gap materials were prepared by the infiltration of liquid crystal polymers with azobenzene side chains and tolane side chains indicating larger birefringence into voids of SiO2 inverse opal films. Linearly polarized light irradiation resulted in transformation from ...
Thus, by fitting an (𝐸−𝐸𝑔𝑎𝑝)𝑛(E−Egap)n curve, the value and the nature of the band-gap can be investigated. In Figure 2, the measurement of the 𝑆𝑖𝑂2SiO2 band-gap can be observed for both the PEELS and VEELS spectra. The VEELS spectrum was accurately ...

In order to determine whether there is any shift of band gap induced by 60Co radiation,using X-ray photoelectron spectroscopy (XPS) data one method for effectively locating such offset is suggested. The XPS data of SiO2 interface at Si3N4/SiO2/Si before and after radiation are analyzed by ...
The occurrence of a photonic band gap modulation in the periodic arrangement of a Si-SiO 2 layer, in the presence of in-plane acoustic plate symmetric modes is studied. The proposed structure shows simultaneous existence of photonic band gaps in the infrared region and phononic band gaps in the...
Experimental confirmation of strong fluorescence enhancement using one-dimensional GaP/SiO2 photonic band gap structure In this paper we report the experimental confirmation of the fluorescence enhancement effect using a one-dimensional photonic band gap (1D PBG) structure. ...

The design, fabrication, and measurement of photonic-band-gap (PEG) waveguides and resonators in two-dimensional photonic crystal slabs have been investigated. Although photonic crystal slabs have only partial gaps, efficient waveguides and resonators can be realized by appropriate design. As regards PB...
