摘要： A laser diode has a horizontal cavity and a mirror attached to the horizontal cavity at an angle of substantially 45° or substantially 135°. The laser diode is mounted on a stem substantially horizontally with taking light vertically emitted to the horizontal cavity as an optical signal, and light horizontally emitted as an optical signal for monitoring, respectively. A photodetector is mounted on the stem substantially orthogonally and so as to let in the optical signal for monitoring.
