Abstract :
Multiple quantum well (MQW) external cavity lasers and optical amplifiers operating in the 1.3 μm optical fiber communications window are described. The device designs and fabrications are discussed. It is demonstrated that MQW devices offer enhanced characteristics when compared with conventional bulk devices. An MQW laser with a single facet coat in an external cavity was measured to have a tuning range of 160 nm from 1.255 μm to 1.417 μm. The device had a peak power of over 40 mW at 1.336 μm, and a side mode suppression ratio of more than 40 dB. An optical amplifier with a length of 500 μm had a bandwidth of 110 nm, a 18 dB single-pass gain, and saturated output power of 14 dBm (25 mW)
