Semiconductor lasers able to emit over the full visible color spectrum have a wide range of practical applications such as solid-state lighting, full-color displays, visible color communications, and multi-color fluorescence sensing. To the human eye, light with a mixture of four monochromatic lasers is visually equivalent to a white illuminant. Current...

Accurate detection and diagnosis of infectious diseases is paramount to appropriate treatment and better outcomes. Despite tremendous efforts to advance new diagnostic techniques, there are still critical gaps in the healthcare system in quickly diagnosing and responding to infectious diseases. Current diagnostic technologies identify pathogens by detecting...
