The unit in motive hole constitutes double-ring fibre core, the hole diameter d of core centre1Control is in 1~4 μ m, two fibre cores pair
It is distributed in fiber optic hub airport both sides with claiming.Using this photonic crystal fiber, two hollow beams can be produced, make this two
Individual hollow beam can produce the three-dimensional light that a center intensity is zero by that can be assembled after a prism at convergence
Field, i.e. bottle beams.The size of bottle beams is relevant with double hollow beam sizes produced by the optical fiber.
The present invention has the following advantages that compared with prior art：
1st, the photonic crystals optical fiber structure is stable, and double hollow beams can be produced in high quality and then local is stably produced
Hollow beam.
2nd, the device overall simple of bottle beams is produced using the photonic crystal fiber, it is easy to adjust.
3rd, can be by changing structural parameters (the fibre core hole diameter d of optical fiber in itself1With covering hole diameter d2) control pair
