Embodiment
Content of the present utility model is made further below in conjunction with accompanying drawing and the preferable specific embodiment of the utility model
Explanation.Example is served only for explaining the utility model, is not intended to limit the scope of the utility model.
As optical signal L enters shown in the microcosmic amplification effect figure in optical filter side in Fig. 3, if parallel optical signal is from filter coating
The outer surface of layer 21 is incident to optical filter 2, then reflected light signal will carry out spread reflection at a slight angle, all the way finally
By after the reflection again and again with multiple optical filters, signal hot spot will be increased progressively the optical signal of outgoing, and then cause
When being mapped on last optical filter, spot signal may exceed the effective clear aperature of optical filter in itself, and then can not 100%
Outgoing, on the contrary it can not be also focused at well at one with other signals, into product common port.
As shown in Figure 4, optical signal L from the antireflective coating 4 of base 1 at an angle it is incident enter base 1 after, light
Signal L continues to transmit forward, through the optical filter 2a of base 1 and first bonding plane, into the first optical filter 2a, then the
Realize the separation of optical signal on one optical filter 2a filter membranous layer, form the first optical filtering signals L0, the first optical filtering signals L0 is penetrated
First optical filter 2a filter membranous layer outgoing, the reflection of remaining optical signal reenter base 1 by the first optical filter 2a, and the bottom of at
Secondary reflection, and then continue across the optical filter 2b of base 1 and second bonding plane again in the high reflection film layer 3 of seat 1, and in the second filter
The separation of optical signal is realized on mating plate 2b filter membranous layer, the second optical filtering signals L1, the second optical filtering signals L1 is formed and penetrates second
Optical filter 2b is emitted, and the reflection of remaining optical signal, is so carried out successively, until realizing the 3rd optical filtering signals L3 to the 7th optical filtering signals
The separation of the road signals of L7 eight, so far complete the wavelength-division function of optical signal.Conversely, the multiplexing function of optical signal can be realized.In we
In case, because the first high high anti-piece 5b of anti-piece 5a and first are high anti-pieces, transmitted therefore, not having optical signal, can only be by institute
There is the optical signal incided on its surface to reflect back.
