BluGlass highlights progress in June quarterly
BluGlass Ltd of Silverwater, Australia — which develops and manufactures gallium nitride (GaN) blue laser diodes based on its proprietary low-temperature, low-hydrogen remote-plasma chemical vapor deposition (RPCVD) technology — has issued a quarterly report on its fiscal Q4/2025 (to end-June).
“BluGlass continued to strengthen its industry recognition during the quarter, securing its first order [worth AUS$230,000] from the Indian Government and being authorized as an approved supplier,” notes CEO Jim Haden. “India is rapidly building its photonics capability with increased investment in cutting-edge research, such as the Solid-State Physics Laboratory. Our partnership with the Indian Government builds on our established development work with the US Department of Defense, and continued conversion of our US$100m project pipeline. While these opportunities are in various stages of maturity, we are continuing to progress technical evaluations and negotiations in line with our long-term project-to-product strategy,” he adds.
“In parallel, we’ve made significant technical progress across our product portfolio [showcased in mid-July at the International Congress on Nitride Semiconductors (ICNS-15) in Malmö, Sweden]. We’ve improved the power conversion efficiency [PCE] of our multi-mode GaN lasers by 16%, approaching our fiscal year 2026 target of 43% CW PCE ahead of schedule. Power conversion efficiency is critical for customers, increasing device longevity and reducing operational costs. Encouragingly, this now brings us in line with several of our large competitors, who have taken many years or decades to reach this PCE performance standard. We believe we can further improve this metric over the coming year. Other technical enhancements include extending our wavelength capabilities with demonstrated aquamarine (488nm) and light green (504nm) wavelengths, as well as improved capabilities of our single-frequency distributed feedback (DFB) lasers,” Haden continues.
“Technical advancements support our conversations with new and prospective defence, quantum and biotech customers, offering advanced precision and tunability in visible wavelengths. Quantum advancements are being underpinned by stimulated light interaction with unique materials, down to the atomic scale, requiring specific wavelengths, and tunability — to target individual atomic interactions. Our modelling collaboration with UCSB [University of California, Santa Barbara] and NCSU [North Carolina State University] is accelerating our development in this domain, enabling us to leverage the world-class skills, capability and expertise of our Microelectronics Commons partner to improve the quality and repeatability of our DFB lasers.”
