A
composite structure hollow anti-
resonance optical fiber disclosed by the present invention comprises an outer cladding layer, a
doping layer and an anti-
resonance layer which are sequentially arranged from outside to inside, the anti-
resonance layer comprises a plurality of glass nested combination tubes which are uniformly distributed along the circumferential direction, are tangent to the
doping layer and are arranged at intervals, and the plurality of glass nested combination tubes surround to form an air
fiber core. The glass nested combined
pipe comprises an outer nested
pipe of a circular structure and an inner nested
pipe of an oval structure arranged in the outer nested pipe. The short half axis of the inner nested pipe is arranged in the radial direction of the
optical fiber, and the outer ring, away from the air
fiber core, of the inner nested pipe is tangent to the inner ring, away from the air
fiber core, of the outer nested pipe. According to the invention, a multi-layer nested structure is adopted, and the anti-
resonance effect is optimized through the cooperation of the
doping layer and the anti-resonance layer with a special structure.
