Fibre array is placed on masterplate, is fallen within by translating stain array in y directions on each bar parallel lines in y directions.Then in x
Translated on direction so that stain array is located at the point of intersection of y directions parallel lines and line A, and it is one-dimensional so to fix first row
The position of fiber array；Secondary series one-dimension optical-fiber array is taken, by being translated in y directions so that its stain array falls within y directions
On each bar parallel lines, and it is opposite one by one with the stain array of first row one-dimension optical-fiber array to fall parallel lines.Then in the x direction
Translated so that stain array is located at the point of intersection of y directions parallel lines and line B.By aforesaid operations, the two one-dimensional light of row are completed
The positioning of fibre array, then carries out fitting and forms 2-D optical fibre array.Again by after the 3 termination fiber stripping of tail optical fiber of 2-D optical fibre array,
Penetrate in the MT optical fiber connectors 4 of 2-D, carry out the end surface grinding of MT again after ultra-violet curing.It is made after above-mentioned flow
2-D optical fibre array device of the present invention.
The special-shaped ceramics of the present invention for being pasted with light transceiving chip array (VCSEL array or photodetector array) 5
6 structure of substrate is as shown in Figure 5.In above-mentioned fiber array device, two row one-dimension optical-fiber arrays have point up and down in height, if
Using flat ceramic bases, then certain optical path difference is had between two row laser beams.The appearance of optical path difference can influence data
Transmission rate, so need change two row chip attachment substrates height.In addition, change shapes of substrates so that array chip
Height is different, can also reduce the distance of fiber array and VCSEL lasers (or optical detector), make light be more easy to assemble, so that
Improve coupling efficiency.
Ceramic bases 6 are integrally formed, and the passage of an indentation are formed by etching, wherein a row light transceiving chip array 5
It is mounted on, another smooth transceiving chip array 5 is then in the substrate raised.The depth capacity of indentation passage is used with photoetching
Laser pulse energy metric density and sweep speed it is related, wherein the general maximum etching depth of Ultra-Violet Laser etching is up to 0.16mm.
