摘要：

High-speed phase modulation (in the frequency bandwidth of 20 GHz, the highest yet reported for MQW phase modulators) for waveguided InGaAlAs/InAlAs multiple quantum well (MQW) optical modulators is reported. The modulator successfully operates at a long wavelength of 1.55-mu-m with a low required voltage for phase shift (V-pi = 3.8 V), small intensity modulation depth below 1.5 dB, and without any modulation bandwidth degradation up to 20 GHz under high input optical power of 0 dBm in single-mode fiber.
