Abstracts of courses

1. Wave optics

Physical basics of optical systems for data collection, storage and transfer are presented. Primary attention is paid to the laws of light reflection, refraction and propagation in anisotropic media. Light propagation in optical fiber and the idea of the optical fiber communication systems are described on this basis. Light interference as well as some of its applications (interference measurement converters, interference filters and demultiplexers) are considered. Idea of moving media optics and measurement converters on this basis is presented.

Inter-modal and material dispersions in fibers are analyzed as well as their influence onto the rate of data transfer via fiber-optical communication lines (FOCL). Waveguide connectors, including the grating and prism type ones, are described. Two-channel directed splitters and other elements of integrated optics are considered as well as their use in FOCL. The means and methods of time and spectral multiplexing are analyzed. Modern schemes of FOCL architecture are considered. Diode light sources for FOCL applications are discussed. In addition, the fiber-optical sensors of various nature are considered.
