Abstract :
A frequency discriminator combining a Mach-Zehnder interferometer with ring resonators is proposed, analyzed and shown to offer a large improvement in linearity without any significant reduction in bandwidth. This can improve the performance of analog optical links by canceling the intermodulation distortion.
