title: Wideband, efficient optical serrodyne frequency shifting with a phase modulator and a nonlinear transmission Line.
abstract: We report shifting of the frequency of an 850 nm laser with an instantaneous bandwidth of (350-1650) MHz and an efficiency between 35% (minimum) to 80% (best at frequencies around 600 and 1500 MHz) by phase modulation with a sawtooth waveform ("serrodyne frequency shifting"). We use a fiber-coupled traveling wave electro-optical modulator driven by a nonlinear transmission line.
