Love this part.

CLAWS Hub development progress BluGlass delivered all quarterly milestones under its Microelectronics Commons‘ CLAWS Hub contract, and is on track or ahead of schedule on all metrics. The Company has made substantial progress against many of next quarter’s deliverables spanning operational, single-mode, and DFB milestones. BluGlass has met yearly single mode electro-optical performance metrics across core 405nm, 420nm, and 450nm wavelengths, and continues to work on refinements. As part of its development activity with the CLAWS Hub, BluGlass has also improved performance of its novel 450nm blue gallium nitride (GaN) DFB lasers. BluGlass, together with development partner the University of California Santa Barbara (UCSB), improved the side-mode suppression ratio of its DFB lasers by 100% since Photonics West 2023, exhibited power output over 100mW from a single diode, and operated at single-frequency over a wide range of current densities. The Company has also reduced operating voltages by 27% over the same period – a key factor in device reliability, thermal management, and wavelength stability.
