Description
Technical Field
The application relates to the field of optical module production, in particular to a dual-fiber array simultaneous coupling packaging assembly, equipment and a method.
Background
Optical modules typically require the use of Fiber Arrays (FAs), which are devices that combine multiple optical fibers together in a specific arrangement. For example, chinese patent publication No. CN112415654a discloses a grating array coupling package structure, comprising: an optical substrate, a first optical fiber, and a photonic integrated chip; wherein the first optical fiber is accommodated on the optical substrate; the first optical fiber is used for transmitting optical signals and comprises an optical outlet for outputting the optical signals; the photon integrated chip comprises a grating coupling element and a waveguide element; the optical substrate is provided with a light reflecting surface at a position close to the light outlet of the first optical fiber; an included angle between a normal line of the light reflecting surface and the transmission direction of the light signal is an acute angle; the light reflecting surface is used for reflecting the light signals output from the light outlet into the grating coupling element; the grating coupling element transmits the reflected optical signal to the waveguide element; the mode field of the grating coupling element matches the mode field of the reflected optical signal. However, in the package of the conventional optical module, when there are 2 or more optical fiber arrays that need to be coupled, the coupling of the transmitting end (Tosa, tx) FA is generally performed first, the Ultraviolet (UV) curing is performed, and after baking in an oven, the FA coupling of the receiving end (Rosa, rx) is performed.
Therefore, the traditional scheme of separate coupling packaging not only needs more time and time to cause low production efficiency; meanwhile, after the coupling of the FA at the Tx end and the FA at the Rx end, the FA at the Rx end is not fixed in the process of transferring from the coupling equipment to the oven, so that free swing is easy to occur in the tray, namely, photodiodes (PIN Diode, PD) or other chips and gold wires on a printed circuit board assembly (Printed Circuit Board Assembly, PCBA) are easy to be carelessly pressed to the surface of the material, meanwhile, the FA at the Rx end is easy to be broken in the process of transferring the material, unnecessary damage is caused to the optical fiber, and the coupling effect is influenced; in addition, if the subsequent process of the Rx end is coupled independently, once a bad product appears, the FA of the Tx end needs to be removed during reworking, and the operation is easy to damage a Photonic integrated circuit (Photonic IntegratedCircuit, PIC) chip of the Tx end, so that the reworking difficulty is high; the substrate materials used in PIC are mainly indium phosphide (InP), gallium arsenide (GaAs), and lithium niobate (LiNbO) 3 ) Etc., are expensive and, once damaged, are costly.
