Description
Technical field
The present invention relates to optical fiber telecommunications system technical field, more particularly to a kind of multichannel light receiving element and reception mould
Block.
Background technology
In high-speed data communication field, for transmission rate request more than 40/100Gbps Networks of Fiber Communications,
In order to overcome the bottleneck of electric signal transmission rate limit, it is ensured that data being capable of long range high-speed transfer, the solution party for generally using
Case is to be modulated the optical signal of 4 road different wave lengths respectively, then wavelength multiplexing/demultiplex for being passed in single-mode fiber
It is defeated.So, the electrical signal rate of each wavelength channel need to only reach 10/25Gbps, you can the signal for meeting 40/100Gbps is passed
Defeated speed.
At present, the light receiving element with four road wavelength channels mainly uses two kinds of optical design schemes：
One kind is the design based on film filtering slice (TFF) technology, generally using structure design side as shown in Figure 1
Case.Mainly include substrate 170, collimation coupled lens 110, speculum 120, TFF (film filter) type wavelength division multiplexer (WDM)
Component 130 (includes 4 wavelength diaphragms 1301,1302,1303,1304, is respectively used to 4 kinds of transmission in the WDM components 130
The optical wavelength signal of wavelength such as 1271nm, 1291nm, 1311nm, 1331nm), focus lens assembly 140 (simple lens or lens array
Row) and the grade of PD components 150 part.Inputs light beam from optical fiber enters WDM components 130 by collimation lens 110, and passes through
After the multiple reflections of speculum 120, in injecting 4 wavelength diaphragms 1301,1302,1303,1304 of WDM components 130 respectively, and then
The light beam of 4 road different wave lengths is separated into via 4 wavelength diaphragms 1301,1302,1303,1304, by focus lens assembly 140
It is respectively focused on the four PD photoelectric detectors 1501,1502,1503,1504 in PD components 150, by PD photoelectric detectors
1501st, 1502,1503,1,504 four road optical signals are converted into four road electric signals, and are carried out a little by the trans-impedance amplifier being connected
Signal amplifies, and realizes the reception of data.Above-mentioned all parts are fixed on the substrate 170 of light receiving element.

Position, so as to the assembling to device is made troubles.Further, since WDM components 130 are designed using discrete WDM diaphragms, its
Relative position with speculum 120 easily changes, and then make light receiving element with the change of temperature and environmental condition
Performance becomes unreliable.
Another kind is the design based on Planar Lightwave Circuit Technology (PLC), i.e., using the array waveguide grating of PLC type
(AWG) four lightwave signals of wavelength are demultiplexed, as shown in Fig. 2 the multi-wavelength light from fiber adapter (being not drawn into figure)
Signal (such as 4 wavelength), is coupled into AWG demultiplexers 220, in corresponding output waveguide (such as by condenser lens 210
4 waveguides) export respectively, corresponding PD or PD gusts of reception is then coupled to by condenser lens (or focusing lens array) 230
On row 240, export electric signal after impedance amplifier 250 amplifies by overstating.The method than foregoing TFF types WDM demultiplexers have compared with
Integrated level high, but fiber adapter, condenser lens 210, AWG 220, condenser lens (or focusing lens array) 230 and PD
