Embodiment Construction

[0033] The present invention will be further described below in conjunction with specific examples.

[0034] combine figure 1 , the embodiment of the present invention mainly provides an integrated all-fiber catenary wave field controller. It is characterized in that: the device is composed of a ring-core fiber 2 with a spiral grating 1, a multimode fiber 3 and a metal film 4 at the fiber end; wherein, the ring-core fiber 2 includes an outer cladding 5, an inner cladding 6 and a core 7 , the graded-index optical fiber 3 includes a cladding 8, a fiber core 9, and a catenary microhole array 10 on the metal film 3 at the fiber end; on the one hand, a circularly polarized input light wave 11 is injected into the ring-core optical fiber 2 to form a fundamental mode 12, Since the spiral grating 1 does not modulate the circularly polarized input light wave 11, the fundamental mode 12 is directly expanded by the multimode fiber 3 and converted into the transmission mode 13, and then...

Abstract

The invention provides an integrated all-fiber catenary wave field regulator. The regulator is characterized by consisting of a section of double-clad fiber 2 with a spiral grating 1, a graded index fiber 3 and a fiber end metal film 4; and the double-clad fiber 2 comprises an outer cladding 5, an inner cladding 6 and a fiber core 7, the graded-index fiber 3 comprises a cladding 8 and a fiber core 9, and a catenary micropore array 10 is arranged on the fiber end metal film 4. The regulator has wavelength and polarization regulation and control capability on a wave field, and when incident wavelengths are respectively a circular polarization input light wave 11 and a circular polarization input light wave 15, the regulator respectively outputs a zero-order Bessel beam 14 and a first-order vortex Bessel beam 17; and when a right-hand circular polarization input light wave 111 and a left-hand circular polarization input light wave 112 are incident respectively, the regulator outputs a non-diffraction zero-order Bessel beam 18 and a strong-focusing zero-order Bessel beam 19 respectively. The regulator can be used in the fields of light field regulation and control, photodynamic therapy, light manipulation and the like.

Description

(1) Technical field [0001] The invention provides an integrated all-fiber catenary wave field controller, which can be used in the fields of generating special light fields, light field regulation, light manipulation and the like. (2) Background technology [0002] As an emerging optical device, optical fiber has achieved great development in the fields of communication and sensing due to its advantages such as low transmission loss, support for long-distance transmission, and large communication capacity. In recent years, with the introduction of the "Lab-on-Fiber" concept, the integration of micro-scale or even nano-scale microstructures with optical fibers has realized microstructure all-fiber devices, which can be used in many strategic fields, from It can be used for long-distance measurement in complex environments (such as human in vivo analysis), signal processing, drug analysis, and super-resolution imaging. Micro-structured all-fiber devices can construct micro-na...
