摘要
FIELD: physics, communication.;SUBSTANCE: invention relates to the field of the fibre-optic technology and can be used in the nonlinear fibre frequency converters of the ultrashort pulses. The microstructured optical fibre for the second-harmonic broadband generation in the infrared optical range of the pumping wavelengths is made of the transparent material and has two air electrode holes located in the cross section of the fibre diameter, and a fibre core located between the electrode holes in the central part of the fibre. The fibre core is formed with the adjoining anode hole and the air holes of the microstructured membrane having a smaller size in comparison with the anode hole located in the cross section between the anode and the cathode holes.;EFFECT: simplification of the fibre manufacturing process, as well as the number minimization of the microstructured membrane holes needed to ensure low-loss of the waveguide mode and optimum overlap of the light-guiding mode with the formation area of the quadratic nonlinearity in the temperature Pauling.;6 cl, 9 dwg, 1 tbl
