Bluglass teams up with Ganvix on VCSELs


Semiconductor development and manufacturing company Bluglass has announced an agreement with US-based laser company Ganvix to develop gallium nitride (GaN) vertical cavity surface emitting lasers (VCSELs.)

In a statement on Thursday, ASX-listed Bluglass said green wavelength (515 to 525 nanometre) VCSELs made with its proprietary remote plasma chemical vapour deposition (RPCVD) process could offer higher performance and brightness. According to the company, such lasers had previously been prohibitively expensive to make out of GaN.

The agreement would see Bluglass paid for its services at a level not considered material, though that would change after successful commercialisation.  

Applications cited included consumer electronics, communications and industrial uses.

“Our unique low temperature, low hydrogen growth technology enables brighter, higher performing green quantum-wells – the key light emitting region in lasers,” Jim Haden, BluGlass President, said. 

“This collaboration highlights the significant competitive advantages of RPCVD, which transform how GaN lasers are made to improve performance. Our collaboration with Ganvix will advance our RPCVD roadmaps and expands our market opportunity.”

Ganvix’s CEO John Fijiol said, ““This significant collaboration to combine nanoporous VCSEL architecture with BluGlass’ unique RPCVD technology provides a path to bring green GaN VCSELs to market.”

The news follows Bluglass’s recent announcement that it has demonstrated feasible reliability of its gallium nitride (GaN) laser diodes, with over 500 hours of continuous operation with stable optical power and voltage in tests.

VCSEL uses include in 3D sensing by lidar, currently in use on vehicles and in phone cameras.
