摘要：

High-speed modulation over 22 GHz for waveguided InGaAlAs/InAIAs mutiple quantum well (MQW) optical modulators is described. A large on/off ratio of over 25 dB has been demonstrated with a low-drive voltage (6V) operating in the 1.55-μm wavelength region. The design and characteristics of MQW p-i-n modulators are discussed. This modulator requires the lowest power yet reported for a high-frequency-operation external modulator. © 1990 IEEE
