摘要：

High-speed, low-driving-voltage operation of multiple-quantum-well (MQW) external modulators based on the quantum-confinement Stark effect (QCSE) operating at long wavelengths are reviewed. We discuss the design and characteristics of ultrafast intensity and phase MQW modulators that have been developed by our group and we compare them with those of other material systems and structures based on a defined figure of merit for external modulators. In addition, we discuss a new integrated light source that enables external modulation of an in-plane DFB laser to reduce wavelength chirping and coupling loss with a laser and a modulator. Finally, we describe new applications for optical soliton poise generation wing the above intensify modulator. (C) 1994 John Wiley and Sons. Inc.
