  This thesis is devoted to develop tunable devices on the base of
one-dimensional photonic crystals (1DPhC) which can sustain Bloch surface waves
(BSWs). First, we explore the possibilities to control the BSW propagation
direction with polarization of incident light. In this case we manufacture
additional passive structures such as gratings on the top of the 1DPhC, which
are working both as a BSW launcher and polarization-controlled wave-splitters.
We test this type of launcher in air and in water as an external medium. Then,
we demonstrate the tunability of the BSW by adding an active layers into the
multilayer stack. Here a crystalline X-cut thin film lithium niobate (TFLN) is
used to introduce anisotropic properties to the whole 1DPhC. Different ways to
manufacture 1D PhCs with LiNbO3 on the top would be described. Finally, we
explore the concept of the electro-optically tuned BSW.
