Abstract
The invention relates to a coupling monitoring method which comprises the following steps that: (1) specific light is input into a single-core optical fiber array; (2) the single-core optical fiber array, a chip and a multi-core optical fiber array are sequentially aligned; and (3) the coupling state is adjusted and judged by observing an optical instrument connected behind the multi-core optical fiber array. The coupling monitoring method has the advantages that the operation is simple and convenient, the alignment precision is improved, the finished product rate is fundamentally improved, and the coupling real-time monitoring effect can be achieved.
Description
Technical field:
The present invention relates to a kind of coupling monitoring method.
Background technology:
Planar waveguide-type optical branching device key property is that input light is averaged distribution, plays the effect of average beam split.The function of beam split is mainly finished on waveguide chip, and input and output side optical fiber is for waveguide that can matching chip, so optical fiber has been made fiber array (FA).Input end is one the road or the fiber array of two-way, and the output terminal way is more, can be 8 cores, 16 cores, 32 cores or 64 cores.
The transmission of light needs medium.Here only in the optical waveguide of optical fiber and chip, transmit,, finish the transmission path of light so optical fiber need be aimed at the waveguide of chip, bonding.Above-mentioned aligning, bonding process are called coupling.
In coupling technique,, be very difficult so fiber array is aimed at the transmission channel of chip because chip inner waveguide and fiber array inner fiber are all very small! If rely on naked eyes that optical fiber is aimed at the chip waveguide, precision does not reach requirement far away, can cause the finished product rate extremely low.
Summary of the invention:
In order to solve the problems of the technologies described above, the invention provides a kind of coupling monitoring method.
The technical solution adopted for the present invention to solve the technical problems is: a kind of coupling monitoring method: (1), import specific light in single-core fiber array; (2), aim at single-core fiber array, chip, multi-core fiber array successively; (3), adjust and judge couple state by observing the latter linked optical instrument of multi-core fiber array.
Advantage of the present invention is: easy to operate, improved the precision of aiming at, and fundamentally improved the flat rate of one-tenth of product.Also can reach the coupling effect of monitoring in real time.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is a synoptic diagram of the present invention.
Among the figure: 1, single-core fiber array; 2, chip; 3, multi-core fiber array; 4, be optical instrument.
Embodiment:
A kind of as shown in drawings coupling monitoring method: (1), in single-core fiber array 1, import specific light; (2), aim at single-core fiber array 1, chip 2, multi-core fiber array 3 successively; (3), adjust and judge couple state by observing multi-core fiber array 3 latter linked optical instruments 4.
In above supervisory system, because optical branching device output terminal passage is more, so can not accomplish output terminal optical fiber is monitored one by one.Because the characteristic of fiber array and chip, spacing between each passage is 250um or 127um, with the spacing of each passage on the chip is consistent, therefore we only need two-way output optical fibre on the limit of multicore FA is monitored, when two passages were in the optimum coupling state on the limit, other passages also just had been in the optimum coupling state certainly so.
