SHAPE TRANSFORMATION OF WAVE BEAMS FALLING ON BRAGG STRUCTURES
Keywords:аpodized quasiperiodic Bragg structure, Goos- Henhen shift, mass center shift, asymmetric resonator.
AbstractThe transformations of the form of wave beams falling on periodic and apodized quasiperiodic Bragg reflectors were considered. Spatial apodization of permittivity contrast of multilayer structures can induce significant decrease of the side lobes. This effect provides much smaller shape deformation of the reflected beam upon incident at angles near the edges of reflection band, as well in Bragg reflection band, in comparison with phenomena in similar periodic structures.
