摘要：

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.
