摘要：

An optical modulator based on an InGaAlAs/InGaAlAs multiple quantum well (MQW) structure is demonstrated. The fabricated device had an extinction ratio 6 dB higher than that of a conventional InGaAsP-based device with similar chirp behaviour. The InGaAlAs MQW effectively improved the performance trade-off between the extinction ratio and chirping parameter.
