· Appl. Phys. Lett.; (United States)
It is demonstrated for the first time that by injection-current control, the lasing wavelength was able to be switched from the lowest (n = 1) quantized state transition to the second (n = 2) transition for a single quantum well laser diode. The separation in energy was as wide as >50 MeV. This novel function of a laser was realized as a result of appropriately increased threshold gain. This diode, moreover, acted as a multiple wavelength-emitting laser.
