ABSTRACT:
A laser diode, which includes a substrate, a laser diode chip bonded on the substrate through a sub-mount, and a monitor element formed on the substrate, monitors laser light emitted from a rear cleavage face of the laser diode chip. The laser diode chip has its front cleavage face covered by a transparent resin. As a result, variations of the surface state of the front cleavage face are prevented.
