Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
By taking a wavelength division multiplex device and 1 point of N planar optical waveguide splitter part are integrated as an example.
The implementation of this programme mainly includes a wavelength division multiplex device, single-core fiber array, planar optical waveguide splitter part,
Multi-core optical fiber array etc..
It is as follows for the specific implementation steps of this programme:
The common end during wavelength-division multiplex is implanted in single capillary or V-groove first, uses uv-curable glue
Single-core fiber array is fabricated to after hydropexis, then by the light-emitting surface of single-core fiber array be polished directly into 8 ° of angles in case
With.Single-core fiber array, planar optical waveguide splitter part and multi-core optical fiber array are placed on the corresponding position of coupling platform.
Debugging light source is adjusted to the λ 1 or λ 2 of wavelength division multiplex device, is linked into the corresponding port of wavelength division multiplex device, then will
The CH1 and CHN of multi-core optical fiber array are linked into light power meter.Under the microscope by single-core fiber array and multi-core optical fiber array
It is separately adjusted to angularly and is aligned with the geometric position of planar optical waveguide splitter part, in fiber array and planar optical waveguide splitter part end
Ultraviolet glue is clicked and entered between face, plays index matching and bonding effect, then passes through the Insertion Loss of monitoring fiber array CH1 and CHN
Insertion Loss is adjusted to open ultraviolet lamp for ultraviolet adhesive curing after minimum value, after solidification, removes device, complete the base of device by value
This production.
Implementation through the above scheme can adjust λ 1 or λ 2 according to the demand of user, can also be according to final application
Scene selects last product encapsulation mode, such as blade inserting, boxlike, machine frame formula etc.；The model of optical splitter can choose 1 point
