Abstract
The authors describe the characteristics of a piezoelectric InGaAs/AlGaAs single quantum well laser with saturable absorber. The screening of the piezoelectric field by injected carriers causes the laser to emit to the blue of the absorption edge. At this wavelength the absorber section is strongly absorbing until the onset of lasing leads to absorption saturation and hence to bistability
