Abstract

Using in situ hydrogen desorption before the growth of the 12nm thick active InGaAs layer over V-grooves, operation of gain coupled DFB lasers at 989nm is achieved al room temperature. As-cleaved lasers, 600 mu m long, have threshold current densities as low as 250A/cm(2) and typical sidemode suppression ratios of 40dB.
