Abstract :
Uncoated, Fabry-Perot (AlGa)As semiconductor lasers are tuned over 105 nm in a grating-coupled external cavity. Broadband tunability is achieved by optimising the resonator loss so as to invoke lasing from both the first and second quantised states of the single quantum well active region.
