A new field of optical research has emerged over the last three recent decades that relates to the optics of periodic structures, with the value of periodicity comparable to the optical wavelength, which has been named photonics. Photonics has revealed many important phenomena that are well applied in the optical wavelength range. The reason for this is related to the fact that virtually all photonics-related effects are within the capacity of experimental observation at the contemporary level of optical techniques, while most of the corresponding effects in the X-ray wavelength range (where photonics was invented in the beginning of 20th century, under the name "X-ray diffraction") are out of the capacity of experimental observation at the present level of X-ray techniques. Photonics researches have shown that many photonics-related optical processes are more efficient than the corresponding processes in homogeneous media; a known example is a low threshold lasing. The photonics terminology proposes the term "photonic crystal", related to a periodic medium whose period value is in the range of the optical wavelengths, in order to distinguish the photonic crystals from the conventional crystals. In the proposed issue, a special type of photonic crystal is studied, namely spiral photonic liquid crystals. This kind of photonic crystal has, at any rate, two essential advantages compared with the conventional crystals. One of them, a theoretical one, is connected with the existence of a simple exact solution of the Maxwell's equations, allowing for the development of an analytical theory of the photonic liquid crystal optics. The second, an experimental one, is connected with the liquid crystal softness, allowing for their parameters to be easily modified by weak external actions (applied electric and magnetic fields, temperature changing, and so on), which is important for achieving a needed set of parameters for the experiment. It is why the studies of the photonic effects in liquid crystals are of interest, not only for the physics of liquid crystals themselves, but also for the whole solid-state physics, because liquid crystals may be regarded as model objects in studies of solid-state effects. The main objects of study for the proposed issue are localized optical modes in liquid crystals, so called, edge (EM) and defect (DM) modes. It was demonstrated that many optical phenomena occurring at the frequencies of localized modes revealed unusual properties that could be used for efficient applications of the corresponding phenomena—for example, efficient frequency conversion, low threshold lasing, and so on. These features are the main reasons for producing the proposed Special Issue. The Special Issue on “Localized Optical Modes in Liquid Crystals” is intended to provide a unique international forum aimed at covering a broad description of the results, involving the optics of photonic crystal as linear or nonlinear, and, especially, lasing. Scientists working in a wide range of disciplines are invited to contribute to this cause.
The topics summarized under the keywords broadly cover examples of the greater number of sub-topics in mind. The volume is open for any innovative contributions involving all aspects of the photonic crystal optics in particular related to the edge (EM) and defect (DM) modes.
