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

垂直腔面发射激光器（VCSEL）是一种高速、紧凑（低成本）的激光二极管，用于激光打印、激光器和其他应用。然而，它们在智能手机的传感和3D成像功能中的实现最近改变了VCSEL市场。该项目将建立在IQE和兰开斯特成功合作开发电信波长（1300 nm）GaSb量子环（QR）VCSEL的基础上。其目标是将发射波长进一步推向红外线，以达到关键的>1400 nm波长范围，使“人眼安全”VCSEL用于消费和汽车应用的下一代接近传感，手势识别，3D成像和LiDAR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.
