Abstract :
A new optical modulator has been fabricated which uses the recently discovered electroabsorption effect in MQW´s. Optical pulses 131 ps long were generated when the device was driven with 122 ps electrical pulses. The input-output characteristics of the device show that it has low insertion loss with reasonable modulation depth and drive voltage.
