Abstract: Provided is a multi-channel optical subassembly. The multi-channel optical subassembly includes a first sub-mount including first and second areas having different thicknesses, a photoelectric device provided in the first area, a circuit board provided in the second area, a second sub-mount inserted into and fastened to the first guide hole and coupled to the first sub-mount, an optical fiber array fixed to the second sub-mount to provide a path through which light emitted from the photoelectric device is received or transferred, and a micro-lens array mounted on the second sub-mount. The first guide hole is provided in one of the first and second areas. The micro-lens array includes a lens collecting the light between the photoelectric device and the optical fiber array.

Abstract: A method of packaging a multi-channel optical receiver module and a package of the same are provided. The method includes installing a first lens on a sub-mount; aligning an optical block including a plurality of filters on the sub-mount; installing the aligned optical block on the sub-mount; aligning a second lens on the sub-mount; installing the aligned second lens on the sub-mount; and coupling the sub-mount to a TO-stem. The aligning of the optical block transmits light incident through the first lens to the plurality of filters, transmits light beams transmitted through the plurality of filters to an object lens, monitors positions of and intervals between the light beams transmitted through an infrared (IR) camera and aligns the optical block so that the intervals between the light beams transmitted through the plurality of filters are identical.
