摘要： 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.

摘要： A mirror-driving mechanism includes a stage having a recessed portion, a base portion in a plate shape, a mirror in a plate shape having a reflection surface configured to reflect light, and a photo detector having a photo detecting surface configured to receive light. The base portion has a through-hole and is disposed so as to cover an opening in the recessed portion. The mirror is disposed so as to be swingable in the through-hole away from a wall surface defining the through-hole. The photo detector is disposed in the recessed portion so as to overlap a region in which the through-hole is located when viewed in a thickness direction of the base portion.
