High power vertical cavity surface emitting lasers with large aperture have been fabricated through improving passivation
lateral oxidation and heat dissipation techniques. Different from conventional three quantum well structure
a periodic gain active region with nine quantum wells was incorporated into the VCSEL structure
with which high efficiency and high power operation were expected. The nine quantum wells were divided into three groups with each of them located at the antinodes of the cavity to enhance the coupling between the optical field and the gain region. Large aperture and bottom-emitting configuration was used to improve the beam quality and the heat dissipation. A maximum output power of 1.4W was demonstrated at CW operation for a 400m-diameter device. The lasing wavelength shifted to 995.5nm with a FWHM of 2nm at a current of 4.8A due to the internal heating and the absence of active water cooling. A ring-shape farfield pattern was induced by the non-homogeneous lateral current distribution in large diameter device. The light intensity at the center of the ring increased with increasing current. A symmetric round light spot at the center and single transverse mode operation with a divergence angle of 16 were observed with current beyond 4.8A.

The periodic gain structure is used as the active region of vertical-cavity surface-emitting lasers
which can enhance the effective coupling between gain regions and internal optical field. The high device performance is achieved. The maximum continuous-wave output power of large aperture device with active diameter up to 400 m is as high as 1.41 W at room temperature. The low threshold current is only 0.5 A
which is lower than that of the conventional device with three quantum wells. 2006 Elsevier B.V. All rights reserved.
