GaN lasers from BluGlass’ Silicon Valley fab meeting or exceeding performance benchmarks
BluGlass Ltd of Silverwater, Australia – which has developed proprietary low-temperature, low-hydrogen remote-plasma chemical vapor deposition (RPCVD) technology – says that gallium nitride (GaN) laser diodes produced at its Silicon Valley production facility are now achieving or exceeding contract manufacturer performance benchmarks.
Testing of BluGlass’ first lasers processed at its Fremont fab are demonstrating electrical and light-output performance in-line or better than previous iterations. These results follow the successful transition of p-side processing from contract manufacturers to its Silicon Valley fab. Reliability testing of these lasers has begun.
BluGlass continues bringing core downstream manufacturing processes in-house, with thinning, cleaving, n-metalization processes commencing, and facet coating well underway. The firm is targeting vertical integration by the end of fiscal-year 2023.
“Vertical integration is key to our commercialization strategy, enabling us to improve our laser quality, consistency and performance while significantly speeding development and reducing production costs,” says president Jim Haden. “This technical milestone demonstrates the importance of operational control in accelerating development turns,” he adds. “Our Silicon Valley production team has commenced work on n-side processing and facet coating capabilities, which is expected to further expedite development, production and improve laser performance and reliability.”
