and radially
polarized Bessel light
beams (BLB) using a one-dimensional photonic crystal with a
nonlinear layer in the unit cell. The method is based on splitting
the spectral dependence of transmission (reflection) of a vectoral
BLB, propagating into periodic medium, on two curves corresponding
to
and
polarized light beams. Owing to this, one can
realize the transmission of BLB with the determined type of
polarization and reflection of another polarized beam. The
conditions are established of the polarization change for
transmitted (reflected) BLB, using controlling pulse. The
elaborated method permits one not only to separate beams with the
azimuthal and radial polarization, but to form their any
superposition. This is achieved by the change of the intensity of
the controlling pulse which results in rebuilding the transmission
spectra of the and beams and, as a consequence, in the control
over the ellipticity of transmitted and reflected Bessel beams.
High-effective and compact optical switches of polarized Bessel
light beams are proposed.
