Having presented a joint paper, with the University of New Mexico, at last years SPIE Photonics West Event, back in March 2020. I got a bit curious as to whether they'd be presenting anything this year? Scheduled to be a digital event between 6-11 March 2021.
Well searching https://spie.org/conferences-and-exhibitions/photonics-west?SSO=1 looks as though their teaming up again with the University of New Mexico with a paper on InAlGaN-based ridge-guide laser diodes using remote plasma chemical vapour deposition for enhanced performance
Abstract InAlGaN-based laser diodes (LDs) can be designed to emit across a wide range of wavelengths spanning UV to green. A common challenge across all wavelengths lies in the difficulty in producing low resistance p-type InAlGaN layers. For shorter wavelength devices, the requirement of high aluminium containing p-AlGaN leads to high device series resistance. For the longer wavelength devices approaching the green wavelengths, the thermal degradation of the indium-rich quantum wells during the growth of the p-GaN and p-AlGaN cladding layers reduces the device efficiency. In this paper we discuss how BluGlass’s remote plasma chemical vapour deposition (RPCVD) technology can address these challenges through improvements to intrinsic material properties as well as enabling novel design architectures.
Should be an interesting read when announced!
Hoping the team will have some hardware to talk about during the event also!
As always DYOR
