Abstract:
1. A semiconductor laser apparatus comprising: a Zener diode containing a first semiconductor region of a first conduction type and a second semiconductor region of a second conduction type joined with the first semiconductor region; the first semiconductor region containing a substrate; a vertical-cavity surface-emitting semiconductor laser diode stacked above the second semiconductor region of the Zener diode and containing at least a first mirror layer of a first conduction type, a second mirror layer of a second conduction type and an active region sandwiched between the first and second mirror layers; a first post that extends from the first mirror layer to the second mirror layer; and a second post that is formed beneath the first post so as to protrude an end of the Zener diode, wherein the first semiconductor region and the second mirror layer are electrically connected and the second semiconductor region and the first mirror layer are electrically connected.
