Abstract :
A new analog fiber-optic link architecture uses a standard Mach-Zehnder electro-optic modulator in lithium niobate with a single RF traveling-wave electrode to achieve linearization across greater than an octave bandwidth. A broadband (800-2500 MHz) link with this new architecture has a measured dynamic range of 74 dB (in an instantaneous bandwidth of 1 MHz).
