FIELD: physics.
SUBSTANCE: this fibre consists of a central waveguide rod of chalcogenide glass, microstructural waveguide shell of alternating plies of said glass and air gaps and second protective microstructural shell of multicomponent glass. Proposed method comprises pre-drawing of rods. Then, chalcogenide insert if formed by laying the rods of chalcogenide glass with appropriate air gaps. Then, outer support capillaries of multicomponent glass are fitted in thick-wall tube of multicomponent glass.
EFFECT: high nonlinearity.
