LASER DIODE UPDATE
o BluGlass’ 405nm lasers have successfully completed the next manufacturing step - optical coating
o Initial tests of unpackaged, coated devices demonstrating target performance
o The Company remains on track to provide sample products to customers in early 2021
Australian semiconductor technology developer, BluGlass Limited (ASX:BLG) is pleased to present an update on its laser diode business with the recent demonstration of strong output power of its standard 405nm laser design.
Laser Diode Product Progress – 405nm coated, unpackaged lasers performing in line with target specifications BluGlass has advanced the development of its first standard laser diode product, with successful completion of the optical coating step of the manufacturing process of several 405nm laser devices. The Company’s 405nm laser design has demonstrated strong initial performance results in line with our target specifications.
405nm Light Output with/without AR-HR Coating
For lasers to achieve optimal performance, the two edge surfaces of the device are coated with specialty optical materials – one to achieve maximum light reflection called the highly-reflective (HR) coating. This is effectively a mirror surface that allows the light to reflect brightly back and forth. The other coating is designed to let the light pass through, while ensuring very little light is lost (the anti-reflective (AR) coating) and to ensure that all light emission occurs from one end.
These specialist AR and HR coatings result in a significant improvement in the light output measured from the device. BluGlass’ 405nm laser output power has more than doubled with the addition of these specialist coatings and are demonstrating strong initial performance specifications in-line with expectations for an unpackaged device.
BluGlass Laser Diode Manufacturing Steps
These devices are now in the process of being packaged at BluGlass’ facility in the US, before further burn-in testing and performance measurements can be completed. At this point, the devices can be tested according to industry standards and generate the final commercial specification of the BluGlass 405nm product design. Additional laser diode designs of other wavelengths and product specifications are also progressing through our development pipeline and various manufacturing steps.
The Company remains on track to provide sample products to customers in early 2021 to meet its technology, manufacturing and commercial milestones in line with its published roadmap.
This announcement has been approved for release by the Board.
