  • Abstract
    Multiple quantum well (MQW) and bulk laser amplifier switches are directly compared by analysis of the switching speed and the wavelength dependence of contrast (extinction ratio) and noise. The MQW device is found to be three times faster, with 20 dB less contrast and 12.5 dB less loss at optimum wavelength. It is thus shown that MQW devices are more suitable for use as fast switches.
