Abstract
As the modulation bandwidth of a traveling wave modulator is increased, the velocities of the microwave and the lightwave need to be taken into consideration. Velocity mismatch of 20 percent or greater can occur in a III-V modulator and this will result in a bandwidth of approximately 22 GHz-cm or less for an electrical loss of 1 dB/GHz sq rt/cm. To improve the bandwidth of the modulator to greater than 40 GHz, velocity mismatch would have to be reduced to within 10 percent. A new velocity matched III-V modulator is presented.
