SELECTIVE SOLDERING METHOD OF THE PHOTONIC CRYSTAL WAVEGUIDE EXTERNAL SHELLS WITH HOLLOW CORE Russian patent published in 2017 - IPC C03B23/18 C03B37/15 

FIELD: nanotechnology.

SUBSTANCE: sample end surface soldering method includes the rotating around a horizontal axis with an angular velocity from 1 to 800 rev^-1, heating upto the temperature not more than 70 °C above the softening beginning temperature of the sample material, the heating is carried out for less than 4 s., after which the sample is cooled by the directed gas flow.

EFFECT: increase of the photonic crystal waveguides with a hollow core percentage output with the uniformly selectively soldered external shells, the stability of the obtained samples during its further chemical modification.
