Integration of a semiconductor laser diode and an optical isolator was studied using the wafer direct bonding technique. A terraced laser diode was fabricated by reactive ion etching using CH4/H2/O2 gas. A smooth and vertical mirror facet was obtained by adjusting the flow rate of the etchant gas. Room-temperature pulsed laser operation was achieved in the laser diode with one cleaved facet and the second facet formed by reactive ion etching. The terraced laser diode was integrated with garnet crystals by wafer direct bonding. Room-temperature pulsed laser operation was confirmed after the bonding process.
