Abstract
In one embodiment, a VCSEL includes a plurality of semiconductor layers, an insulative region, a resistive region, and a remainder region. The semiconductor layers include a lower mirror, an active region, and an upper mirror. The active region is disposed over the lower mirror and includes a first lasing region. The upper mirror is disposed over the active region. The insulative region and the resistive region are integrally formed in the semiconductor layers. The remainder region includes the semiconductor layers except for the insulative region and the resistive region integrally formed in the semiconductor layers. The insulative region is disposed between the resistive region and the remainder region.
