Abstract :
We analyze ring resonator-based traveling-wave modulators that show high modulation efficiency at frequencies around multiples of the free spectral range. The modulators have better tolerance for the optical/microwave velocity mismatch and the loss of the microwave transmission line than traveling-wave Mach-Zehnder modulators.
