More Information
Summary:Structures and active alignment methods thereof of a Transmitter Optical Sub-Assembly (TOSA) Structure are provided, that includes a light source sub-assembly including a light source component assembled on a light source bench; an optical sub-assembly including an optical component assembled on an optical bench; and a silicon chip including a coupler. A light emitted by the light source component is received by the coupler via the optical component along an optical path, the light source bench and the optical bench are thermally conductive to dissipate heat. The light source sub-assembly and the optical sub-assembly are actively aligned at the same time to optimize optical coupling between the light source sub-assembly and the optical sub-assembly by optimizing positions and a distance of the light source sub-assembly and the optical sub-assembly, the positions and the distance are flexibly adjusted during the active alignment process.
