The Violet Frontier: Bandgap Engineering of the 405nm Laser Diode

Janeiro 17, 2026 9

The 405 nm wavelength sits at the strategic intersection of the visible and ultraviolet spectrums. Unlike the more common infrared Gallium Arsenide (GaAs) based emitters, the 405nm laser diode is a product of Gallium Nitride (GaN) semiconductor t...
