Abstract
Measurements are presented which demonstrate that multiple-quantum-well (MQW) lasers can offer significantly lower noise and distortion levels than equivalent double-heterostructure lasers. Improvements of approximately=10 dB in the laser intensity noise and approximately=8 dB in the second-harmonic distortion have been achieved. These figures are close to the predicted improvement of approximately=12 dB expected in MQW lasers as a result of doubling the laser resonant frequency.<>
