Detailed description of the invention
Fig. 1 is the structural schematic diagram of the light emission component with multiple wavelength channel signals.
Specific embodiment
The light emission component with multiple wavelength channel signals include laser array, laser collimator lens component, thoroughly
Mirror assembly, isolator group, light-integrating subassembly and fiber port.As shown in Figure 1, laser array include four lasers, four
A adjacent laser be a light emitting group: laser 111 to 114 form LD array, laser collimator lens component include with
One-to-one four collimation lenses of four lasers of laser array: 121 to 124, transflector mirror assembly includes and laser
The one-to-one four transflector mirrors of four collimation lenses of collimator lens assembly, transflector microscope group have a pair of of transflector mirror 141,
142 mirror settings, and it is respectively present the transflector mirror 131,132 that is in the same direction arranged adjacent with the two transflector mirrors, mirror image is set
Extinction piece 150 is equipped between a pair of of the transflector mirror set, which may be set to be spacer, avoid light mixing.Isolation
Device group includes two isolation with polarization rotator being separately positioned on after the transflector mirror 141 of mirror settings, 142 transmission planes
Device 160A, 160B, light-integrating subassembly include the light combination reflecting mirror 133 and light combination transflector mirror 170 after being located at isolator, light combination
For the reflecting surface of transflector mirror 170 against the reflecting surface of light combination reflecting mirror 133, fiber port 190 is directed at light combination transflector mirror 170
Transmission plane.The light combination reflecting mirror 133 of light-integrating subassembly is high-pass filtering piece, and light combination transflector mirror 170 is polarized composite wave piece.Light combination is saturating
The optically focused coupled lens 180 as optical fiber end collimation lens are equipped between reflecting mirror 170 and fiber port 190.
Specifically, the transflector mirror 131,132 that is in the same direction arranged adjacent with the transflector mirror 141,142 of mirror settings is anti-
The face of penetrating is respectively toward to the transflector mirror 141,142 of its respective mirror settings.
Specifically, transflector mirror assembly and light-integrating subassembly are all that 45 degree of inclination angles are placed.
The light emission component with multiple wavelength channel signals, transflector mirror 131,132 are the 45 of conventional S-band reflection
Optical filter is spent, transflector mirror 141,142 is used as light splitting piece, and light combination transflector mirror 170 is used as PS wave multiplexer.From swashing in LD array
The optical signal that light device 111 to 114 issues is respectively quasi- by the collimation lens 121 to 124 in lens array respectively along optical axis
Directly.The optical signal that laser 111 issues arrives after as the total reflection of the transflector mirror 131 of high-pass filtering piece as 1 channel signal
Up to the rear surface of the transflector mirror 141 as light splitting piece, which is reflecting surface；The optical signal that laser 112 issues is as 2
The half energy of channel signal merges after penetrating transflector mirror 141 with 1 channel signal.1,2 channel signals after merging pass through band
After the isolator 160A of polarization rotator, linear polarization is rotated by 90 °, and becomes S light from initial P light, is used as high pass through another

Wave.Mirror image therewith, the optical signal that laser 114 issues is as 4 channel signals by the transflector as high-pass filtering piece
3 channel signals that the optical signal issued after the total reflection of mirror 132 with laser 113 obtains are in the transflector mirror as light splitting piece
Then 142 rear surface multiplex is remained unchanged by another isolator 160B rear polarizer direction with polarization rotator, through work
For after the light combination transflector mirror 170 of PS wave multiplexer with 1, the 2 photosynthetic waves of channel S after above-mentioned reflection.Last four road signal is via poly-
Burnt coupled lens 180 are coupled into optical fiber 190, complete signal output.
The light emission component with multiple wavelength channel signals be provided with a pair of of mirror settings transflector mirror 141,
142, and it is respectively present the transflector mirror 131,132 that is in the same direction arranged adjacent with the two transflector mirrors 141,142, adjacent two
The light of a transflector mirror 131,141 and 132,142 is accumulated isolator 160A and 160B respectively, the then conjunction in light-integrating subassembly
Light reflection mirror 133 and light combination transflector mirror 170 photosynthetic are sent to optical fiber end what two isolators 160A and 160B were exported to be a branch of
Mouthful.The light emission component with multiple wavelength channel signals, four wavelength signals use mirror settings facing each other, pass through
Light path design makes four wavelength signals finally realize unified multiplex after the light combination transflector mirror 170 as PS wave multiplexer, leads to
Cross reverse thinking structure abbreviation be it is numerous so that the single-item performance requirement sharp fall of each combination optical components, thus
The sharp fall in cost is brought, to reduce high speed device and Module Price, the landing as early as possible of high speed optical communication is pushed to do
Positive contribution is gone out.
