Description

TECHNICAL FIELD

[0001] The present application belongs to the field of optical devices, and particularly relates to a manufacturing method of an optical device and the optical device. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute the prior art.

[0003] With the popularity of the Internet and the increasing demand, the corresponding access network needs to be upgraded to meet the high requirements of network access rate. In the process of upgrading the access network, the TO packaging specifications of the laser and photodetector, the optical coupling structure, and the process difference and cost of OSA device coupling are considered.

[0004] At present, the main body of the optical device structure is manufactured in batches by the powder metallurgy process, which has the following shortcomings: once the design is finalized and the mold is changed, it is difficult, costly and time-consuming, so batch powder metallurgy relies on sufficient early structural design verification. Early design verification is in the form of machining. Due to the complex and compact internal structure of the OSA device, and the high machining process and precision requirements, the traditional machining method can only achieve some simple structure designs, or designs that do not affect the overall precision and assembly process simplicity of the OSA device after splitting.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0034] Figure 1 A flow chart of a manufacturing method of an optical device of an embodiment of the application is given. In combination with Figure 1 , a manufacturing method of an optical device of the present embodiment comprises:

[0035] S100: determining an internal optical structure of the optical device according to a simulated optical path and a packaging specification;

[0036] S200: designing an assembly seat structure of the optical device according to a coupling assembly process of the internal optical structure of the optical device;

[0037] S300: split the component seat structure of the optical device into each component seat substructure, so that each component seat substructure is a corresponding maximized machinable manufacturing structure;

[0038] S400: adopt a machining method to manufacture each component seat substructure for assembling each component seat substructure and fixing the corresponding optical structure.

[0039] The embodiment splits the component seat structure of the optical device into each component seat substructure, and makes each component seat substructure a corresponding maximized machinable manufacturing structure, which is suitable for optical devices of different structures, realizes the predetermined design requirements by simple machining manufacturing method, meets the requirements of simplifying subsequent assembly process and ensuring precision, and quickly realizes the design verification of new structure optical device.

[0040] In step S100, the simulation optical path and the packaging specification are both pre-design requirements; and the process of determining the internal optical structure of the optical device is the prior art, which is not described here in detail.

[0041] In step S200, in the process of designing the component seat structure of the optical device, in addition to considering the coupling assembly process, the environmental factors for manufacturing the optical device are also considered to ensure the precision of the optical device.

[0042] In step S300, the structural strength of each component seat substructure after assembly meets the overall strength preset requirements of the component seat structure of the optical device. Moreover, each component seat substructure meets the foolproof design principle.

[0043] In the specific implementation process, a step-by-step splitting and judging method is adopted to split the component seat structure of the optical device.

[0044] The process of the step-by-step splitting and judging method is as follows:

[0045] In each step of splitting the component seat structure of the optical device, it is judged whether each substructure obtained by the current splitting step is a machinable manufacturing structure. If yes, the corresponding substructure stops splitting; otherwise, it continues to split. In this way, the maximized machinable manufacturing structure can be accurately determined, the requirements of simplifying subsequent assembly process and ensuring precision are met, and the design verification of new structure optical device is quickly realized.

[0046] Among them, in each step of splitting the component seat structure of the optical device, if any substructure obtained by the current splitting step is an un-machinable manufacturing structure, it is further judged whether the un-machinable manufacturing structure is caused by itself.

[0047] If the non-machinable structure is not machinable due to its own reasons, the non-machinable structure itself is split; otherwise, the structure interfering with the non-machinable structure is split. Thus, by analyzing the reasons of the non-machinable structure, the way of structure splitting is simplified as much as possible, and the design and verification of the complex structure are realized.

[0048] In one or more embodiments, an optical device is made using the steps in the method of making an optical device as shown in Figure 1 .

[0049] The optical device of the embodiment includes an assembly seat and corresponding optical structures fixed thereon; the assembly seat is assembled by machining each assembly seat substructure.

[0050] In the embodiment, the assembly seat is a metal structure, and the structure of the assembly seat of the optical device is as shown in Figures 2-4 The left small block part of the assembly seat structure of the optical device is a part excavated inside the assembly seat structure of the optical device. The embodiment uses the way of simplifying structure splitting as much as possible to realize the design and verification of the complex structure.

[0051] For example, in the optical device, the 0-degree filter sink is of a circular profile. In the optical device, the 45-degree filter base needs to be split out for machining due to the requirements of the bevel angle and surface precision; the profile of the 45-degree filter base is of a cuboid, which can ensure assembly positioning and facilitate machining.

[0052] The cuboid cross section uses a fool-proof design with different width and height dimensions, and the four side edges can use a round corner with an inner groove R0.55 mm and an outer corner R0.70 mm (which can also be adjusted according to actual needs), which can avoid the fact that the machining inner 90-degree right angle surface cannot guarantee the tool head clearance angle and facilitate subsequent assembly and precision implementation.

[0053] In the specific machining process, the 45-degree filter base right angle edge is as much as possible to be a circular groove, which is also convenient for one-cut forming during machining. Since the bottom of the 45-degree filter base has an anti-reflection groove, machining must penetrate to the two side faces to be able to be machined, and therefore, the tolerances and the thinnest dimension need to be considered to realize machining.

[0054] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
