It can be seen that when the preparation temperature decreases a blue shift of transmission peak occurs, while the transmissivity of incident light, corresponding to the first Bragg condition peak, increases simultaneously.
The use of Green's function is more powerful than looking for the transmission peak.
The variation of intensity of the transmission peak versus anodization temperature has also been investigated.
However, within the testing waveband, no obvious transmission peak was observed in the samples.
We also discuss the rules of the transmission peak of these fractal PCs.
As the refractive index n increases, both the transmission peak and dips exhibit a redshift.
Transmission peak shifts to longer wavelength as the size and rate of aggregation increases.
Furthermore, by varying the energy splitting, the linewidth and the position of the ultranarrow transmission peak can be engineered.
The transmission peak is defined as the one that nearly reaches the unit transmission of the forbidden band.
In the vicinity of the PIT transmission peak, it offers large positive group delays indicating the slow light effect.
Furthermore, the transmission peak of the nanosphere silica AR coating can be controlled by varying the LB deposition parameters.
