BluGlass Limited (ASX: BLG) has efficiently demonstrated working tunnel joint laser diodes in a world-first proof-of-concept using its proprietary remote plasma chemical vapour deposition (RPCVD) technology.
The unique laser diode prototypes take advantage of BluGlass' unique RPCVD passage junction innovation, created over several years for usage in high-power items including laser diodes and also high-brightness LEDs.
Created to enable greater power and also extra reliable lasers for use in business applications such as 3D printing as well as industrial welding, these RPCVD passage junction laser diode models have demonstrated excellent lasing behavior. This milestone assists verify the possibility of the RPCVD laser diode creates to deal with the crucial performance requirements for high-value gallium nitride (GaN) laser diode applications.
GaN laser diode applications in the industry are presently restricted by optical and also resistive loss in the magnesium-containing layers (the p-type layers) which results in reduced conversion performances, commonly in the 40-45% array contrasted to the near 90% in GaN-based LEDs. Practically 50% of the power consumed when running GaN laser diodes is lost in the form of heat due to the extremely resisting p-type layers, traditionally required to create the electrical circuit in a laser diode.
BluGlass' unique strategy, allowed by the special benefits of reduced temperature, reduced hydrogen RPCVD growth can eliminate the demand for these highly resistive as well as performance shedding p-type layers. RPCVD allowed novel layouts to replace the p-type cladding layer with an RPCVD tunnel joint and also a 2nd n-type cladding layer-- called a double n-wave laser diode, leading the way to considerably boost laser diode performance in the future.
The Firm will remain to optimize its RPCVD tunnel junction laser diode layout, epitaxy, and manufacture to increase laser efficiency.
BluGlass Executive Chair James Pedestrian said "This is a crucial recognition of the possibility of our unique RPCVD and tunnel joint modern technologies. This accomplishment is a testament to the efforts of our leading-edge team in developing a series of innovative laser diode products, including this world-first demonstration of dual-n-wave lasers. This has the possibility to transform exactly how laser diodes are made to aid bring GaN lasers into a new period.
"While these novel lasers have actually significant growth needed before the launch of future RPCVD enhanced items; our considerably further innovative standard (MOCVD) laser diode product growth remains to focus on solving dependability and also improving our downstream production ahead of releasing business items to waiting customers."
