METHOD FOR SELECTIVE SOLDERING OF EXTERNAL SHELLS OF PHOTONIC CRYSTALLINE WAVEGUIDES WITH HOLLOW CORE Russian patent published in 2017 - IPC G02B6/255 C03B37/15 

FIELD: physics.

SUBSTANCE: invention may be used to obtain samples of photonic crystalline waveguides with hollow core (PCW with HC). The method of soldering the end surface of the sample involves heating the sample with a specific source of thermal action. In this case, a photonic crystalline waveguide with a hollow core is selected as the sample, a specific heat source is rotated around the axis of the waveguide at an angular velocity from 1 to 500 rpm^-1, the sample is heated to a temperature, exceeding the temperature of the softening starting point of the sample material by not more than 80°C, heating is carried out for not more than 4 seconds, after which the sample is cooled by a directed gas flow.

EFFECT: increase in the percentage of output of photonic crystalline waveguides with a hollow core with uniformly selectively soldered external shells, as well as ensuring the maximum uniformity of properties and the stability of the resulting samples during their further operation.
