Abstract: Provided is a multi-channel optical module device. The optical module device includes: a light source unit configured to include a plurality of laser diodes that are capable of wavelength modulation according to current; a beam splitter unit configured to include a plurality of beam splitters that have different reflectivity and transmissivity and reflect or transmit light output from each laser diode of the light source unit to output them in a first direction or a second direction; and an optical coupler configured to couple and output the light from the beam splitter unit. Center wavelengths of the laser diodes of the light source unit are different from each other, and the number of output channels varies according to the number of laser diodes.

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.
