BluGlass presenting paper at Photonics West on manufacturing high-performance lasers using RPCVD

BluGlass Ltd of Silverwater, Sydney, Australia – which develops remote-plasma chemical vapor deposition (RPCVD) technology for the manufacture of high-performance semiconductor devices – says that its head of epitaxy, Dr Josh Brown, is presenting ‘High brightness MOCVD-grown laser diodes using RPCVD tunnel junctions’ (paper 11262-26) at the SPIE Photonics West 2020 conference at 10:30am on 3 February (room 203, Level 2 South, Moscone Center) in San Francisco, CA, USA. BluGlass is also exhibiting at booth 4783.

In October, BluGlass launched a new direct-to-market business unit (managed by VP of business development Brad Siskavich in the firm’s US office) to leverage the advantages of RPCVD tunnel junctions for GaN laser diode applications.

“The potential to apply what we’ve learned with LED tunnel junctions has been validated by a university partner, modelling our design for RPCVD epitaxial growth techniques,” says Siskavich. “This collaboration has also stress-tested some of the assumptions and some of the results of our own lab work in Sydney,” he adds.

“We continue that work and we’ll be sharing more at Photonics West. At the same time, we will start manufacturing laser diodes using existing MOCVD techniques later this calendar year, using the expertise we have developed over the past decade, and we will continue to research how tunnel junctions grown using RPCVD can be deployed in the future in laser diode manufacture,” continues Siskavich.

“BluGlass is also building the downstream supply-chain that will allow us to launch our new test facility in the US later this year. Together, these operations form the core of a customizable, end-to-end market approach that will enable BluGlass to generate growing revenues in the high-value laser diode market,” he believes.

The focus of the paper is high-brightness MOCVD-grown laser diodes using RPCVD tunnel junctions. BluGlass says that its RPCVD process has already delivered breakthroughs in the growth of tunnel junctions for high-performance LEDs, and that these also apply to laser diode devices. RPCVD tunnel junctions can hence enable a novel way of growing laser diodes, addressing optical losses and resistive losses in particular.
