Research output: Contribution to conferencePaperpeer-review


A frequency modulation discriminator which consisted of a Mach-Zehnder interferometer with ring resonators in its arms was proposed. The ring resonator was an 'all pass' filter with precisely needed phase response. Results indicated that a 7 dB improvement in the dynamic range was possible without paying a bandwidth penalty. The device offered complete cancellation of third-order inter-modulation distortion without affecting the bandwidth.
