Cavity length dependence of the wavelength of strained-layer InGaAs/GaAs lasers.

The lasing wavelength of a strained-layer InGaAs/GaAs single quantum well laser has been found to depend strongly on the cavity length. The relationship between the lasing wavelength and the cavity length was established experimentally and a cavity length tuning mechanism for a quantum well laser is thus made possible.
