Abstract
It is shown that multielectrode pumping allows a significant increase in the output power of quantum well SLDs in the broad spectrum operating regime. More than 60nm spectral width at output power ranges from 2 to 23mW was obtained by two-electrode pumping of the active region of AlGaAs SQW SLD. The possibility of controlling the form of the SQW SLD spectrum by multielectrode pumping and central wavelength switching of a 20nm FWHM (Gaussian profile) over 40nm is shown. The coherence length of the SLDs estimated using the Mandel approach is 7mm at 2mW output, increasing to 11mm at 23mW.
