BluGlass reports on latest laser diode prototypes
Lasing results look good but there is need for additional work on post epitaxy production to improve long term reliability
Australian semiconductor developer BluGlass has received the latest results of testing for its laser diode development.
The prototype laser diodes are showing lasing results consistent with commercial specifications for output power and wavelength, demonstrating the soundness of the BluGlass wafer epitaxial process.
However, reliability testing has demonstrated weaknesses with the post epitaxy production steps, with gradual loss of light output due to degradation of the optical facet of the BluGlass laser chip when operated to high power in continuous wave conditions.
While disappointing, the results confirm that BluGlass’ core laser diode design is working to specification, and the challenges the company is facing are in production steps involving third party providers. As an historically R&D business, these steps are new to BluGlass, but also well understood in the industry generally, and hence BluGlass is confident that they can be solved expeditiously.
BluGlass intends to place all of its short-term focus on resolving the reliability issue, and over the coming year on all aspects of the production supply chain to scale commercial grade products needed by the market – to be demonstrated by customer orders of our product. Given the nature of the challenge, the company intends to seek additional experienced assistance in the post epitaxial phase of development, from those with established production capabilities from the industry.
To ensure the success of this phase of work, the company proposes to undertake a non-renounceable rights Issue to current shareholders to raise up to $8 million. The company is finalising the terms of the offer and it is expected that the terms and accompanying Offer Booklet will be released to the market prior to the commencement of trading on Wednesday 9 June 2021.
Proceeds from this offer will ensure sufficient financial runway to secure the necessary resources, and to allow the required development time to apply those resources, and secure initial customer orders.
After 13 years at BluGlass, Giles Bourne has advised the company of his intention to step down as managing director and CEO, effective immediately. James Walker, BluGlass Chair said: “During his time at the helm, Giles has built a globally focussed semiconductor research business, which is poised to move into its next stage of its growth."
James Walker will take on the role of executive chair as the company undertakes a search for a new CEO.
