Description

Title: Apparatus and method for alignment of an optical component with a further optical component Description According to a first aspect, the present disclosure relates to an apparatus for alignment of an optical component with a further optical component provided in an optical component package. According to a second aspect, the present disclosure relates to a method for alignment of an optical component with a further optical component provided in an optical component package. The role of photonics is growing due to the growing amount of data that is related for instance to cloud computing. This growth is accompanied by an increase in energy consumption for supporting the infrastructure. The current infrastructure relies predominantly on data transfer via copper infrastructure. The power consumption of a data communication architecture based on an optical infrastructure using photonic integrated circuits will be relatively low compared to a copper based communication architecture.
The growth of the use of photonic applications appears to be hampered by the relative high cost of the photonics applications and the infrastructure needed for manufacturing the photonics applications. The relative high cost are at least partly due to the relative high cost for packaging and termination of optical fibers. Whereas the front end processing of the photonics applications may benefit from existing processes for manufacturing microelectronics, the processes available for back-end processing, packaging and termination of for instance optical fibers are limited. The objective of the present disclosure is to provide an apparatus allowing to realise a photonics application at relative low cost.
This objective is realised by the apparatus according to the first aspect of the present disclosure.

The method and apparatus according to the present disclosure will next be explained by means of the accompanying schematic figures. In the figures: Fig. 1: an apparatus according to the present disclosure is shown; Fig. 2: a top view of the apparatus of Fig. 1 is shown; Fig. 3: a front view of the apparatus of Fig. 1 is shown; Fig. 4: a cross-section in more detail of the apparatus of Fig. 1 is shown in more detail; Fig. 5: an isometric cross-section view of the apparatus of Fig. 1 is shown in more detail; Fig. 6: a method according to the present disclosure is shown.
Figures 1 — 5 show different views of an apparatus 1 for alignment of an optical component 3 with a further optical component provided in an optical component package 5, according to a first aspect of the present disclosure.
In this embodiment, the optical component 3 is a fiber pigtail. The fiber pigtail is an optical waveguide with a sub-assembly having a predetermined optical connector on one end and a length of exposed fiber at the other end. The fiber type may be a SMF-28 fiber with a 9 um core or a MultiMode fiber with a 50 ym core and can have any type of fiber tips, like lensed, tapered, drawn, etc. The further component may be a photonic chip integrated in an optical component package 5.
The apparatus 1 comprises an optical receiving unit 7 arranged for receiving the optical component 3 and an optical package receiving unit 15 arranged for receiving the optical component package 5.
The apparatus 1 is mounted on a stable base 29 to eliminate vibration in between the hardware. The stable base 29 is placed on a damped platform to eliminate vibrations caused by the environment in which the apparatus 1 is placed.
On the stable base 29 a rotation unit 17 is placed arranged for transporting the components 3, 5 for assembly from a receiving position A into a process position B, by rotating the platform around an axis 19. The optical component receiving unit 7 and the optical package receiving unit 15, for receiving the fiber pigtail 3 and the optical component package 5 respectively, are fixed to the rotation unit 17. At the receiving position A, components 3, 5 which have to be aligned are loaded. Components 3, 5 which are already aligned, are unloaded from the apparatus 1 at position A. The fiber pigtail 3 and optical component package 5 are either loaded and unloaded by hand by an operator or automatically by a robot. The optical component receiving unit 7 comprises a vacuum gripper for keeping the fiber pigtail 3 in position during transport. The optical package receiving unit 15 comprises a mechanical clamping mechanism for keeping the optical component package 5 in position.
At process position B a first alignment unit 9 is arranged for taking the optical component package 5 over from the optical package receiving unit 15. The first alignment unit 9 is a high accurate motion system, for example a PI motion hexapod MC12 with Nano Cube arranged for receiving the optical component package 5 and for lifting the optical component package 5 from the rotation unit 17 for the alignment process. Moving the optical component package 5 from the rotation unit 17 eliminates vibrations when a further component 3, 5 is loaded or unloaded simultaneously from the rotation unit 17 at position A.
The apparatus 1 further comprises a determining unit 4 and a control unit 6. The control unit 6 is communicatively coupled to the first alignment unit 9 and the determining unit 4. To be able to read out coupled light from fiber pigtail 3 into the optical component package 5, a coupling unit 13, connected to the determining unit 4, automatically couples the optical connector of the fiber pigtail 3 mechanically and optically through an optical connector of the coupling unit 13 with the determining unit 4 when the components 3, 5 are at position B. The coupling unit 13 is connected at one channel to a light source comprised by the determining unit 4 and at another channel to a power measurement unit comprised by the determining unit 4.
The apparatus 1 further comprises a XYZ robot 24 arranged for moving in three directions X, Y and Z over the process position B. Mounted on the XYZ robot 24 are a detection unit 23, for example a machine vision camera, for initial course alignment of the fiber pigtail 3 to the optical component package 5, a fixation unit 21, for example an adhesive dispense unit, arranged for fixating the fiber pigtail 3 with the optical component package 5 after realising the alignment and a UV-curing unit 22, arranged for curing the fixation adhesive, mounted on XYZ robot 24 arranged for moving in three directions X, Y and Z over the process position B.
During the alignment process, the optical component package 5 is lifted from the rotation unit 17 by the first alignment unit 9. The optical component package 5 is kept in place on the first alignment unit 9 by a vacuum gripper. The first alignment unit 9 is arranged for moveing the optical component package 5. The fiber pigtail 3 is maintained stationary on the table by a vacuum gripper. The connectors of the fiber pigtail 3 and the coupling unit 13 are automatically connected and via an optical fiber connected to the determining unit 4 in such a way that the one channel of the fiber is connected to the light source and the another channel of the fiber connected to power measurement unit.
The detection unit 23 moves over the process position B for an initial and course alignment by determining the offset between the exposed fiber tips of the stationary positioned fiber pigtail 3 and the optical component package 5. The detection unit 23 is communicatively coupled to the determining unit 4 and control unit
6. In a single camera shot features of both the fiber pigtail 3 and the optical component package 5 are captured and an initial position for the optical component package 5 is determined. The control unit 6 controls a second alignment unit for moving the optical component package 5 to the initial position. In this initial position, both elements 3, 5 are aligned to each other within a positional accuracy in the order of several um, preferably within 1 um.
After providing the optical component package 5 in the initial position, the active alignment of the optical component package 5 with the stationary fiber pigtail 3 is initiated. During the active alignment, light from the light source comprised in the determining unit 4 is transmitted through the fiber pigtail 3 and the aligned optical component package 5 and measured back into the power measurement unit comprised in the determining unit 4. During the active alignment, the optical component package 5 is moved in front of the fiber pigtail 3 by the first alignment unit 9 in all directions while measuring the optical power by the power measurement unit.
The measured optical power is determined as a parameter related to the positional accuracy of the alignment of the optical component package 5 with the fiber pigtail 3. The first alignment unit 9 is controlled by the control unit 6 taking in account the determined measured optical power related to the positional accuracy of the alignment.
During the active alignment a map of the measured optical power is generated out of which the optimal position of the optical component package 5 is determined by PI algorithms.
After realising the alignment, the optical component package 5 is fixated to the fiber pigtail 3 by the fixation unit 21. With the use of the detection unit 23, the fixation unit 21, mounted to the XYZ robot 24, is moved based on machine vision coordinates.
Subsequently, adhesive comprised by the fixation unit 21 is dispensed onto the components 3, 5. Dependent on the type of adhesive, different types of dispensers can be selected, like a pressure time dispenser, jet dispenser or micro shot needle valve dispenser.
The adhesive is cured by the UV-curing unit 22, for which the UV wavelength, UV intensity and UV source orientation is selected dependent of the type of adhesive and based on the application.
After successfully realising the accurate alignment and fixating of the optical component package 5 to the fiber pigtail 3, the assembly of the optical component package 5 and fiber pigtail 3 is unloaded from the apparatus 1 without disturbing the optical interconnection between the optical component package 5 and the fiber pigtail 3. The connectors of the fiber pigtail 3 are disconnected from the coupling unit 13, preferably before unloading the fiber pigtail 3 from the optical component receiving unit 7, and the fiber pigtail 3 is released from the optical component receiving unit 7. The terminated package is lowered back, by the first alignment unit 9, onto and clamped by the rotation unit 17. The rotation unit 17 transports the assembly of the optical component package 5 and fiber pigtail 3 to the receiving position A, where the assembly of the optical component package 5 and fiber pigtail 3 is unloaded from the apparatus 1 by either an operator or a robot gripper.
The cycle time of terminating the package is less than 30 seconds resulting in an exit rate of the machine of 1 assembly per 30 seconds with an alignment accuracy of less than 100 nm.
Figure 6 shows a method 101 for alignment of an optical component 3 with a further optical component provided in an optical component package 5 according to a second aspect of the present disclosure relates. Method 101 comprises a step 103 of receiving the optical component 3 by the optical component receiving unit 7. A subsequent step 105 of method 101 is receiving the optical component package 5 by the first alignment unit 9.
Method 101 further comprises the step 107 of determining, by the determining unit 4, a parameter related to a positional accuracy of said alignment of said optical component 3 with said further optical component. During a subsequent moving step 109, by the first alignment unit 9, the optical component package 5 taking into account the measured optical power realises the alignment of the fiber pigtail 3 with the optical component package 5.
