Australia-based semiconductor developer says its 405nm model is approaching commercial specification.

Sydney, Australia-based semiconductor technologies developer BluGlass, has demonstrated working 405nm, 420nm and 450nm laser diode designs.

The company, which describes itself as dedicated to bringing to market a breakthrough in the LED lighting industries, added that its 405nm product development is now “approaching commercial specifications.”

Its statement, released this week, said, “Manufacturing supply chain qualification for 2in production is on schedule to complete in the current quarter; the Company remains on track to deliver sample products this calendar year; initial customer revenues are anticipated from early 2021.”

BluGlass’s laser diode business unit has made progress in all three of its development areas: technology; product development; and manufacturing preparedness.

The company statement also reveals more details about the 405nm laser development: “Our 405nm design is showing good performance, approaching commercial specifications in brightness. These results have been verified through multiple fabrication vendors, as we qualify both our laser diode designs and our manufacturing supply chain simultaneously.

“The process to manufacture a laser diode involves many complex steps, supplied by various specialist vendors. These devices are being simulated and modelled, designed, and then grown on wafers at our manufacturing facility. They are then shipped to the US for multiple wafer processing steps including cleaving before final optical coating, packaging and burn-in testing.”

Target customers and markets

The company says that there are several target customers, ranging from global research institutions requiring custom laser development to OEMs and distributors. BluGlass is establishing collaborative customer relationships to develop customised solutions in several of its target markets.

BluGlass noted that recent product developments resulting from wafers grown earlier in 2020 were initially delayed due to supply chain impacts caused by the Covid-19 pandemic: “As a result, we have diversified our supply chain, and are qualifying multiple providers in each segment of the supply chain around the world to help mitigate future delays and ensure that we are working with the best suppliers in each segment.”

Further to this, the statement added, “processing timelines from design and epitaxial growth through to initial testing has now been significantly expedited. Full supply chain qualification is expected to complete on schedule in the current quarter. Our US test facility is now fully operational. Our US based team has grown with the addition of two, industry experienced, expert laser diode testing engineers.”
