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.

垂直腔表面发射激光器 (VCSEL) 是高速、紧凑（低成本）激光二极管，用于激光打印、数据通信和其他应用。然而，它们在智能手机传感和 3D 成像功能中的应用最近改变了 VCSEL 市场。该项目将建立在 IQE 和 Lancaster 成功合作开发电信波长（1300 nm）GaSb 量子环（QR）VCSEL 的基础上。目标是将发射波长进一步推向红外，达到“人眼安全”VCSEL 的关键 >1400 nm 波长范围，用于下一代接近传感、手势识别、3D 成像和 LiDAR 设备，供消费者和消费者使用。汽车应用。
