Abstract

An optical assembly that installs red, green, blue laser diodes (LDs) within a single package is disclosed. The LDs are mounted on a base via respective sub-mounts. Light emitted from the LDs is collimated by collimating lenses and multiplexed by two wavelength filters so as to align optical axes of the light. The multiplexed light has an axis substantially leveled with the axes of the red, green, and blue light measured from the top of the base.
