Abstract

High dynamic range is achieved in the optical domain with our technique thereby providing multi-gigahertz modulation bandwidth. Early measurements show an improvement exceeding 24 dB in third-order intermodulation distortion over that of a single, unlinearized Mach- Zehnder optical modulator. Using this approach, practical measurements at 500 MHz show a spurious-free dynamic range (SFDR) of 105 dB Hz^2/3, where the noise floor spectral density is -141.3 dBm/Hz measured at the optical link output.
