Abstract
The performance characteristics of amplitude modulated coupling (AMC) phase-shifted MQW DFB lasers emitting near 1.55 mu m are reported for the first time. The AMC is obtained by the holographic double-exposure technique, it provides single longitudinal mode oscillation up to 78 mW for I=500 mA. This result confirms that AMC flattens the power distribution along the laser cavity. Linewidths as low as 600 kHz have been obtained for cavities as short as 600 mu m at P=15 mW.
