Background technology
In 40G and 100G optical modules, partial wave generally to be carried out to the light of multichannel different wave length or ripple, this splitting/composing is closed
Ripple component is built in optical module, as little as possible to volume requirement, while optical property (such as insertion loss, isolation etc.) also has
Very high request.
In order to realize that small product size is little, then part is carried out integrated, the integrated micro of conventional eight passages as far as possible
Wavelength-division and multiplexing assembly are learned, as shown in fig. 1, is using following structure：Eight passage integrated micro-optical wavelength-divisions and multiplexing assembly, its
The principle of wavelength-division function is that a string of flashlights are incident to substrate 1 in left side, and specified signal is transmitted from the right side of optical filter 5d, other
Signal is reflexed on highly reflecting films 2 in optical filter 5d left surfaces, and realizes secondary reflection again, by this alternating reflex, often through one
Optical filter, just has a specified optical signal to transmit away, so as to realize wavelength-division function, otherwise realizes multiplexing function.It is wherein high anti-
The effect of ejected wave piece 4 is exactly to provide two secondary reflections to optical signal, so as to reach the purpose that eight optical signals are divided into two groups.
Conventional eight passage integrated micro-optical wavelength-divisions and multiplexing assembly, there is a longer high reflection wave plate centre.Due to producing
The assembly precision of product has high demands, and the processing of little optical filter itself is also the presence of certain tolerance, for this reason, it may be necessary to it is difficult to while right
Eight optical filters and a high reflection wave plate carry out precise positioning, and one-time fix.Assembling fixture difficult design, assembling product
Operation difficulty is also big, and production yield is low.
To reduce the impact of optical filter and high reflection wave plate processing dimension tolerance, in assembling, need with high reflection wave plate
First position and as benchmark, four optical filters are respectively assembled in both sides.This requirement causes jig Design to become increasingly complex.
Utility model content
The purpose of this utility model is to solve the assembling difficult problem that difficulty is big, production yield is low, is proposed optical filtering bit end
A middle high reflection wave plate is cancelled, and makes into be directly coated with the scheme of a highly reflecting films in substrate relevant position, so as to realize eight
Individual optical filter can be divided to two groups of assemblings and fixation, reduce assembling difficulty.
This utility model solves the technical scheme of its technical problem employing：A kind of integrated micro-optical wavelength-division of eight passages with
Multiplexing assembly, including substrate, the first filter set and the second filter set, the incident side side of the substrate is coated with the first high reflection
Film, the light emission side side of the substrate are provided with the first filter set and the second filter set, first filter on the substrate light emission side side
The second highly reflecting films are coated between mating plate group and the second filter set.
Further, the plating film length of second highly reflecting films is integer of the optical signal in two neighboring reflection dot spacings
Times.
Further, the reflective side of the substrate and the angle on the base of substrate are 82.0 degree ± 0.1 degree.
Further, the first described filter set and the second filter set are long by four pieces of filtration Different lightwaves respectively
Filter set into.
The beneficial effects of the utility model are：Product structure of the present utility model is relatively easy so that assembling product fixture
Design difficulty also decrease.Assembling fixture design can be designed to be grouped assembling fixture, also can one assembling fixture, behaviour
Make simpler；If finding after assembling bad, it is only necessary to carry out single group and disassemble doing over again, another set optical filter will not be involved.

Specific embodiment
Content of the present utility model is made further below in conjunction with accompanying drawing and the preferred specific embodiment of this utility model
Explanation.Example is served only for explanation this utility model, is not intended to limit scope of the present utility model.
As described in Fig. 2 to Fig. 3, a kind of integrated micro-optical wavelength-division of eight passage described in this programme and multiplexing assembly,
Including substrate 1, the first filter set 3 and the second filter set 5, the reflective side of the substrate 1 is coated with the first highly reflecting films 2,
The light emission side side of the substrate 1 is provided with the first filter set 3 and the second filter set 5, first filter on 1 light emission side side of the substrate
The second highly reflecting films 6 are coated between mating plate group 3 and the second filter set 5；The plated film of the second highly reflecting films 6 described in this programme
Length is integral multiple of the optical signal in two neighboring reflection dot spacings, and specifically the plating film length of the second highly reflecting films 6 is energy
A string of optical signals are carried out once above integral multiple enough completely to reflect；The reflective side of the substrate 1 described in this programme and substrate 1
The angle on base be 82.0 degree ± 0.1 degree；In this programme, the first described filter set 3 and the second filter set 5 are distinguished
Be by four pieces filtration Different lightwave length filter set into.
When being embodied as, on the 1 former position for fixing high reflection wave plate 4 of substrate, the second highly reflecting films 6 are directly coated with.Such as
This, eight passage integrated micro-optical wavelength-divisions only need to assemble eight optical filters with multiplexing assembly.In assembling, can direct root
