Long wavelength (>1400 nm) GaSb quantum ring VCSELs for consumer applications

垂直腔面发射激光器（VCSELs）是高速，紧凑（低成本）的激光二极管，用于激光打印，数据通信和其他应用。但是，最近在智能手机的传感和3D成像功能上的应用改变了VCSEL市场。该项目将建立在IQE和兰开斯特大学之间成功的合作基础上，开发电信波长（1300nm） GaSb量子环（QR） vcsel。目标是将发射波长进一步推向红外，以达到“眼睛安全”vcsel的关键波长范围，该波长范围将用于下一代近距离感应、手势识别、3D成像和消费和汽车应用的激光雷达设备。

Vertical-cavity surface-emitting lasers (VCSELs) are high-speed, compact (low cost) laser diodes used in laser printing, datacoms and other applications. However, their implementation in the sensing and 3D imaging functions of smartphones has recently transformed the VCSEL market. The project will build on successful collaborative work between IQE and Lancaster developing telecoms wavelength (1300 nm) GaSb quantum ring (QR) VCSELs. The objective is to push the emission wavelength further into the infrared to reach the crucial >1400 nm wavelength range for 'eye-safe' VCSELs to be used in the next generation of proximity sensing, gesture recognition, 3D imaging and LiDAR devices for consumer and automotive applications.
