Problems solved by technology

However, for the above-mentioned four-piece optical device, due to the need for multiple coupling alignment and welding to complete power coupling and equalization, the equipment needs to have more complex coupling degrees of freedom to ensure that each component has a high coupling accuracy. So as to ensure that after multiple couplings, the overall coupling deviation is still within an acceptable range

However, the existing optical device coupling and welding equipment usually has insufficient coupling freedom. The four-piece optical device needs to be coupled multiple times separately, the packaging efficiency is low, and the coupling accuracy of the equipment is not high, resulting in the optical device after packaging. The power is significantly reduced, which ultimately affects the packaging quality of optical devices
