Semiconductor developer BluGLass Limited (ASX: BLG) has proved the feasible reliability of its gallium nitride (GaN) laser diodes, demonstrating more than 500 hours of continuous operation with stable optical power and voltage in reliability testing.
Reliability feasibility is valuable in the production and commercial phase as it enables BluGlass to increase its engagement with potential customers as well as a critical step in beta production and product launches. Improvements in reliability are directly attributable to enhance metals, facets, and bonds with newer iterations currently progressing through the supply chain.
Commenting on the announcement, BluGlass CEO said:
“Demonstrating reliable laser diodes is a significant milestone, reflecting the suitability of our lasers for use in a vast number of applications. Commercial reliability is not a one-size fits all approach, varying greatly depending on the application.
“At one end of the spectrum, we have single-use applications such as pyrotechnics, which require one-shot reliability and good ‘shelf-life.’ At the other end of the spectrum are very sophisticated space-based and industrial applications, which often require reliability of more than 10,000 hours and even years of operation. Many applications, including medical and scientific applications, require less than 1,000 hours’ reliability”
“Reliability testing is ongoing and with our recent achievements and progress, we are moving toward a fixed beta design. This reliability milestone also enables us to increase our engagement with customers who are eagerly awaiting products to meet unmet market needs.
“Encouragingly, we have achieved these results with older iterations made by our contract manufacturers. We expect current iterations featuring new epitaxy designs and enhanced processing through our Silicon Valley fab will demonstrate improved yield, reliability, and performance as we continue to refine our laser diodes ahead of product launches.”
