Abstract
The present invention relates to fiber communication technology, which is particularly to suitable for a manufacture occasion for a single mold tail fiber collimator in a key part-self-focusing lens tunable light filter in dense light wave square multiplexing. The technology reaches the axial symmetrical coupling state between a single mold tail fiber and a self-focusing lens by regulating the distance and the coupling state between the single mold tail fiber and the self-focusing lens when return light detected by a monitoring device is a maximum value, the monitoring device is composed of a single mold fiber coupler and an optical power meter, and then the axial symmetrical coupling state is fixed. The performance of the resonant cavity of the collimator manufactured by utilizing the method is much superior to the performance of a resonant cavity of a collimator manufactured by utilizing a non-quantization method for finding a reference by visual light.
Description
The present invention relates to a kind of Fibre Optical Communication Technology, be specially adapted to a kind of critical piece in the intensive optical wavelength-division multiplex---the making occasion of single-mode tail fiber collimating apparatus in the GRIN Lens Fabry-Perot adjustable light wave-filter.
Self-focusing lens type Fabry-Perot resonator cavity is made up of the P/4 GRIN Lens of a pair of band single-mode tail fiber, directly is coated with Dielectric High Reflective Films and forms the Fabry-Perot resonator cavity on the opposing end surface of two GRIN Lens.This GRIN Lens also is that collimation focuses on coupling element.Influence a making that key factor is the single-mode tail fiber collimating apparatus of this GRIN Lens Fabry-Perot chamber adjustable light filter performance.Various single-mode tail fiber collimating apparatuss all will be made the single-mode tail fiber end face earlier: optical fiber is inserted bonding oven dry behind the contact pin body, fixedly fastens with metal, then on anchor clamps with its end surface grinding polishing, and guarantee that the fibre core optical axis is vertical with fiber end face.The single-mode tail fiber collimating apparatus that is used for self-focusing lens type Fabry-Perot adjustable light wave-filter structurally is different from the single-mode tail fiber collimating apparatus of conventional coupling usefulness, because the former autohemagglutination lens interface is coated with the medium high-reflecting film.Past generally adopts visible light (as the He-Ne ruddiness of 632.8nm) to make the single mode fiber collimator of optical communication window 1.31 μ m or 1.55 mum wavelengths, wavelength is different will introduce suitable error because operation wavelength is with adjusting, make two collimating apparatuss that constitute resonator cavity can not reach the requirement of rotational symmetry coupling separately, or can not reach confocal coupling when forming resonator cavity, the mismatch that causes in the chamber introducing certain incident angle or cause the chamber internal schema has a strong impact on the peak transmission characteristic and the fineness in F-P chamber.About self-focusing lens type Fabry-Perot adjustable light wave-filter, existing many documents were made report, as H.Schmuck etc. " Low Loss SM Fiber-Pigtailed GRIN-Lens Fabry-PerotType Filter for widely Variable Free Spectral Range " ECOC89-585, but the method for making of single-mode tail fiber collimating apparatus is not wherein seen openly.
At the shortcoming that above-mentioned prior art exists, task of the present invention provides a kind of method for making of single-mode tail fiber collimating apparatus.
Technical scheme of the present invention is, this single-mode tail fiber collimating apparatus is a kind of optical element, and it is made up of GRIN Lens and a single-mode fiber of a P/4, is the rotational symmetry coupling between optical fiber and the lens.Because of the light from the optical fiber outgoing expands the Shu Biancheng directional light behind the P/4 lens, so two collimating apparatuss can be carried out fibre to fine, point-to-point coupling, make the single-mode tail fiber end face earlier: bonding oven dry behind the optical fiber insertion contact pin body, fixedly fasten with metal, on anchor clamps, its end surface grinding is polished then, and guarantee that the fibre core axle is vertical with fiber end face.The technical measures that the present invention takes are regulated for directly adopting the light of collimating apparatus operation wavelength, utilize waiting of GRIN Lens to reflect end face, the rotational symmetry of carrying out between optical fiber and lens with autocollimatic method is coupled, it is characterized by: connect by the single-mode fiber order between a. light source and optoisolator, the single-mode optical-fibre coupler, light power meter detection port and optoisolator connect with one side at single-mode optical-fibre coupler respectively, and the single-mode optical-fibre coupler another side connects with single-mode tail fiber; B. single-mode tail fiber and GRIN Lens with P/4 of highly reflecting films are clamped on the high-accuracy micropositioning stage with anchor clamps respectively; C. regulate distance and couple state between single-mode tail fiber and GRIN Lens, when the return light that detects until single-mode optical-fibre coupler and light power meter is maximal value, then reach single-mode tail fiber and GRIN Lens rotational symmetry couple state between the two; D. with optics viscose glue or metallization packaged technology tail optical fiber and GRIN Lens are combined securely then.
Advantage of the present invention is, adopts two single-mode tail fiber collimating apparatuss of the present invention, can form the Fabry-Perot resonator cavity through suitable adjusting.Test findings shows, under similarity condition, the Fabry-Perot resonator cavity superior performance that the collimating apparatus that the Fabry-Perot resonator cavity that adopts this method to make is made than the non-quantization method of looking for benchmark with visible light constitutes many.
