Bluglass secures DFB laser order


Customer will use450nm DFB prototypes for testing in the development of next-generation defence, aviation, and scientific applications

Australia-based semiconductor developer BluGlass has secured its first purchase order of alpha GaN Distributed Feedback (DFB) lasers. The customer is a pioneer in photonic and fibre-based laser technology, and will use BluGlass’ blue prototype DFB lasers in the development of defence, aviation, and scientific applications.

Quantum sensing, navigation, and computing applications are driving significant demand for compact single-frequency laser light sources, such as GaN DFB lasers. Single frequency visible lasers have unique characteristics required to stimulate quantum transitions for highly promising military and commercial applications, including advanced robotics, bio-medical applications, and atomic clocks for quantum navigation.

In addition to quantum applications, the unique performance properties of single-wavelength visible lasers will also enable advancements in ranging and underwater communication, gas sensing, stand-off threat detection, and high-performance spectroscopy applications. GaN DFB lasers are an ideal candidate to facilitate the strict frequency, beam fidelity, narrow linewidth, and the high power and efficiency these next-generation technologies require.

BluGlass is one of the first companies in the world to develop viable DFB lasers in GaN, as part of its partnership with the University of California Santa Barbara’s SLEEC Consortium.

BluGlass CEO Jim Haden said: “Our first customer order of BluGlass prototype GaN DFBs reflects the significant interest in these ultra-precision lasers for quantum, defence, and commercial applications. Novel capabilities such as DFB lasers form a key pillar of our growth strategy, and we will continue to leverage our RPCVD technology to enhance BluGlass’ DFB lasers, achieving advanced single frequency performance at blue wavelengths and beyond.”
