PURPOSE: A high-output single-mode VCSEL(Vertical Cavity Surface-Emitting Laser) device and a fabricating method thereof are provided to oscillate only a transverse mode by controlling independently a current flow region and an optical induction region. CONSTITUTION: A high-output single-mode VCSEL device includes an active region(23), an optical guide layer(24), the first bottom mirror layer(25), a current confinement layer(26), the second bottom mirror layer(27), an optical induction oxide layer(28), and a current confinement induction oxide layer(29). The active region(23) is formed with a top mirror layer and a quantum well layer, which are laminated on a semiconductor substrate. The optical guide layer(24) is formed by depositing an oxide layer on the active region. The first bottom mirror layer(25) is formed on the optical guide layer to form a part of the bottom mirror. The current confinement layer(26) is formed on the first bottom mirror layer to control a current flow region. The second bottom mirror layer(27) is formed on the current confinement layer to form a part of the bottom mirror. The optical induction oxide layer(28) and the current confinement induction oxide layer(29) are formed by performing an oxide formation process.
