摘要	An optoelectronic device such as a vertical cavity surface emitting laser (VCSEL) includes a tunnel junction that conducts a current of holes tunneling into an active region. Tunneling in a selected area of the tunnel junction is disabled to form a current blocking region that confines the current to desired regions. Tunneling can be disabled in the selected area using techniques including but not limited to implanting or diffusing dopants, disrupting crystal structure, or etching to remove part of the tunnel junction.
其他摘要	诸如垂直腔表面发射激光器（VCSEL）的光电器件包括隧道结，该隧道结传导隧穿进入有源区的空穴电流。禁止在隧道结的选定区域中的隧穿以形成将电流限制到期望区域的电流阻挡区域。可以使用包括但不限于注入或扩散掺杂剂，破坏晶体结构或蚀刻以去除部分隧道结的技术在所选区域中禁用隧穿。
主权项	An optoelectronic device comprising: an active region; a semiconductor region; a tunnel junction between the active region and the semiconductor region; and a current blocking region between the active region and the semiconductor region, wherein the current blocking region operates as a reversed biased PN junction and confines a current between the active region and the semiconductor region to the current through the tunnel junction.
