Acoustic-optical interaction in photonic crystals: Frequency dependence of Bragg angle

A method is developed for calculating the frequency dependences of the Bragg angle in two-dimensional photonic crystals for isotropic and anisotropic Bragg diffractions. It is shown that the frequency dependences of the Bragg angle exhibit some interesting features related to the formation of partia...

Zusammenfassung:	A method is developed for calculating the frequency dependences of the Bragg angle in two-dimensional photonic crystals for isotropic and anisotropic Bragg diffractions. It is shown that the frequency dependences of the Bragg angle exhibit some interesting features related to the formation of partial forbidden bands of optical and acoustic waves.
