Photonic structures in a form of the waveguide channels, with periodic spatial changes in refractive index in the wavelength scale, are typically manufactured based on well-developed silica and gallium arsenide technology [1], as well as with use of the high-precision lithography. The main disadvantage related to practical application of such devices is that their optical properties cannot be altered after fabrication. Due to this fact, liquid crystalline periodic waveguiding structures, manufactured with use of the photo-polymerization process, have been proposed in this work. Importantly, propagational characteristic of such photonic structures can be easily adjusted during fabrication procedure, and then may be also dynamically tuned by e.g. applied external voltage, as presented in this communication.
