Description

technical field [0001] The invention relates to the technical field of laser and silicon waveguide coupling, in particular to a coupling device with an electrode clamp for coupling a laser and a silicon waveguide. Background technique [0002] Photonic integration technology generally refers to the integration of active devices (lasers, detectors, optical amplifiers, optical modulators, etc.) and passive devices (light splitter / combiner, optical filter, optical multiplexer / demultiplexer, etc.), In this way, a single-chip multi-functional optical device technology is realized. Photonic integration technology is considered to be a powerful optical module technology in the near future and even in the future, especially in short-distance optical interconnection applications such as data centers. However, coupling the light from single-mode lasers to planar optical waveguides or other silicon-based optical integrated chips is still a big topic at present. Coupling is also known...

Problems solved by technology

[0003] At present, the coupling platform is often used to couple the laser with the optical waveguide. Due to the high precision requirements of the coupling, the position accuracy of the material in the coupling device will directly affect the accuracy of the subsequent coupling. At present, the coupling process has the following problems: 1. The size of the laser component and the optical waveguide component is small, and it is difficult to observe during the coupling process; 2. The light emitted by the laser component is not easy to accurately align with the optical waveguide, and it is not easy to adjust the angle of the emitted beam; 3. The clamp strength should not be too strong during coupling positioning Large so as not to damage the laser components or optical waveguide components and to facilitate powering the laser
