The Time and Frequency Measurement Standards of Ukraine

The problems of maintenance of the primary measurement standard of the units of time and frequency and national scale of coordinated time of Ukraine (UTC (UA)) are considered, set of measurement standards, its metrological characteristics, comparing results of national scale of the coordinated time of Ukraine with international time scale and time scales of other countries standards are described, participation in forming the international scale of atomic and coordinated time is highlighted. The complex and peculiarities of realization the secondary measurement standards of Ukraine are considered

Waveguide magnetoplasmonic structure based on ferrite garnet film

The magnetoplasmonic structure, which is a planar multimode magnetooptical waveguide, 10 μm thick with plasmon resonance SiO2 / Cu coating on the surface is experimentally realized. With the total length of the magnetooptical waveguide 4.6 mm and the length of the SiO2 / Cu coating equal to 3.9 mm, the insertion loss of the structure for TM- and TE-polarized light was 22 and 4 dB, respectively, at a wavelength of 1550 nm. Linearly polarized light was launched into the magneto-optical waveguide using a SMF-28 single-mode optical fiber coupled to the polished input edge of the waveguide. The structure is of interest for use as miniature magnetically controlled modulators of light intensity
