摘要

This study explores an alternative approach to fabricate the 850 nm SiO_x-planarized ring-shape vertical-cavity surface-emitting lasers (VCSELs) with stable lasing emission and high-speed operation. The fabricated ring-shape VCSELs have an inner oxide diameter of 9 μm and an outer oxide diameter of 15 μm. These devices show a threshold current of 3.65 mA, a maximum light output power of 7.5 mW at 25 mA, and a differential resistance of 65 Ω at room temperature. Furthermore, they exhibit a stable dual-mode behavior over the operation current of 25 mA. Moreover, this TO-packaged 850 nm VCSEL for small-signal analyses shows a maximum modulation frequency of about 8 GHz, which is corresponding to a modulation-current efficiency factor of 2.47 GHz/mA~(1/2). This VCSEL also shows a clear and symmetric eye-opening feature at 10.3 Gbytes/s and 18 mA for back-to-back and 66 m transmission tests. Based on these results, the excellent high-speed performance can be fulfilled by the SiO_x-planarized and TO-packaged oxide-confined VCSELs with ring-shape geometry.
