A gourd optical fiber for transmitting hollow light beams

Abstract

The invention discloses a hoist optical fiber for transmitting hollow light beams and belongs to the technical field of optical fiber structure design. The hoist optical fiber includes an air fiber core, a fiber core anti-resonance single ring, a quartz supporting frame, a cladding air layer and a quartz cladding layer; the fiber core anti-resonance single ring forms an anti-resonant wall; and a fiber core is filled with air, so that the air fiber core can be formed; and the quartz supporting frame is adopted to support the fiber core anti-resonance single ring. The wall thickness of the fibercore anti-resonance single ring, the position of the joint point of the quartz supporting frame and the fiber core anti-resonance single ring, the size of the joint point and the wall thickness of the quartz supporting frame can be adjusted, and therefore, the hollow-core anti-resonance single ring used for blue-detuned atomic guide can be realized. The hoist optical fiber is small in transmission confinement loss and is simple in structure, and therefore, the hoist optical fiber can better transmit the hollow light beams, and the interaction area between light and atoms and the guiding efficiency of the atoms can be improved, the realization of an experiment of blue-detuned atomic guide can be benefitted, and a high-precision atomic interference gyroscope can be realized.

Description

technical field [0001] The invention belongs to the technical field of optical fiber structure design, and in particular relates to a "cucurbit" optical fiber for transmitting hollow light beams. Background technique [0002] Hollow-core anti-resonant fiber is a new type of microstructured fiber that guides light through leaky modes. When the transverse propagation constant of the grazing light in the core does not resonate with the silica cladding, it can be regarded as a broadband guide. A light window, which generally has a large structural size and a simple cladding structure. The light-guiding path is established in the air core, which can perfectly solve the inherent defects (non-linearity, dispersion, photo-induced damage, etc.) of the traditional solid-core fiber. The uniqueness of this structure and light guiding mechanism makes the hollow core antiresonant fiber have many characteristics different from traditional optical fibers, such as broadband light guiding an...

Problems solved by technology

[0005] In order to solve the problem that the blue-detuned guide atoms cannot be carried out in the hollow-core anti-resonance fiber, the present invention proposes a "cucurbit" optical fiber for transmitting hollow beams, specifically the hollow-core anti-resonance for the blue-detuned guide atoms Optical fiber, the anti-resonance single ring of the fiber core constitutes an anti-resonance wall in the "cucurbit" fiber, and the air core is filled with air to form an air core, and the anti-resonance single ring of the fiber core is supported by a quartz support frame. The wall thickness of the anti-resonance single ring, adjusting the quartz support frame, adjusting the size of the joint point and the position of the joint point of the fiber core anti-resonance single ring, and adjusting the wall thickness of the quartz support frame are used to realize the hollow core anti-resonance for blue detuning guide atoms. resonant fiber
