Vertical Cavity Surface Emitting Lasers (VCSELs) are commercially important with an increasing range of applications and are required over an increasing range of wavelengths. While shorter wavelengths are in commercial manufacture VCSELs emitting at 1300nm and longer wavelengths are not readily available even at the shorter end of the range. This stems from a failure to understand the active region materials necessary for these wavelengths and associated degradation processes. The project will focus on developing efficient processes for new materials such as dilute nitrides, antimonides and bismides for long wavelength operation. We envisage new device designs resulting in excellent laser performance and also uniformity and yield over large area substrates. Students will utilise modelling packages such as nextnano and photon design for device design and a series of advanced characterisation techniques for materials and devices for understanding results before developing new device concepts. These long wavelength VCSELs with high beam quality are expected to dominate Comms, LIDAR and other measurement applications.

垂直空腔表面发射激光器（VCSEL）在增加的应用范围内在商业上很重要，并且在不断增加的波长范围内需要。虽然波长较短，但在1300nm发射的商业制造VCSEL中，即使在该范围的较短端也无法使用更长的波长。这是由于未能理解这些波长和相关降解过程所必需的活性区域材料。该项目将着重于开发新材料的有效过程，例如稀氮化物，抗杀菌剂和二晶剂，以进行长波长操作。我们设想新的设备设计，从而在大面积基板上具有出色的激光性能以及均匀性和屈服。学生将利用建模软件包（例如NextNano和Photon Design）进行设备设计，以及一系列用于材料和设备的高级特征技术，以在开发新设备概念之前了解结果。这些具有远光灯质量的长波长VCSEL预计将主导COMM，LIDAR和其他测量应用。
