BluGlass presents RPCVD laser diode paper at Photonics West

At the virtual SPIE Photonics West 2021 conference (8–11 March), BluGlass Ltd of Silverwater, Australia – which develops remote-plasma chemical vapor deposition (RPCVD) technology for the manufacture of high-performance semiconductor devices – is showcasing its latest laser diode product development progress and custom GaN epitaxy services with customers and industry participants.

The firm is hosting a virtual booth, where technical staff are available throughout the conference to chat live and answer questions on product development, custom GaN services and the advantages of remote-plasma chemical vapor deposition (RPCVD) material growth.

RPCVD is a low-temperature, ammonia-free approach to GaN-based epitaxial growth, with advantages not possible with conventional metal-organic chemical vapour deposition (MOCVD), it is claimed.

Registered conference attendees can visit the virtual booth at the SPIE Photonics West Digital Marketplace or book a meeting with senior technical staff via the SPIE Connect portal.

Also at the virtual conference, head of epitaxy Dr Josh Brown is presenting a new paper ‘InAlGaN based ridge-guide laser diodes using remote plasma chemical vapour deposition for enhanced performance’ outlining recent laser diode development work, utilizing both the industry-incumbent MOCVD technology and the firm’s unique low-temperature RPCVD technology to enhance the performance of laser diodes.

The paper highlights the benefits of BluGlass’ proprietary RPCVD technology for the manufacture of both traditional and novel structure laser diodes. It features the firm’s latest MOCVD laser diode development results and progress on the development of enhanced laser diode structures utilizing RPCVD.

BluGlass says that its RPCVD technology offers laser diode manufacturers a number of performance and cost advantages for the growth of high-brightness GaN laser diodes, including higher-performing devices.

High-brightness GaN laser diodes are used in a growing number of applications including industrial lasers (cutting and welding), scientific applications, automotive, and general lighting and displays.

BluGlass says that it continues to advance its MOCVD standard laser diode product suite ahead of its first product launches (405nm and 420nm laser diodes) in early 2021. It also continues to advance its RPCVD low-resistivity p-GaN and tunnel-junction laser diode designs for enhanced laser products.
