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.
