Enabling Lightwave Electronics with Nanotechnology: Synthesizing Attosecond Waveforms from Frequency Combs Generated in Ferroelectric Photonic Structures
Abstract
The goal of this project is to demonstrate the synthesis of femtosecond to subfemtosecond time scale electric waveforms of arbitrary shape in a compact setting. We demonstrated in this project that periodic-poled photonic structures for cascaded multiharmonic generation can be reliably reproduced with our poling technique which exhibits the nanometer precision that the process requires. We have identified an ultrabroad band acousto-optic modulator (programmable dispersion filter) that is compact and will shrink the dimensions of our waveform generator by more than a factor of ten. We successfully tested this modulator and showed that it has good diffraction efficiency throughout the entire multioctave bandwidth of our light source and time synchronization for phase modulation has been accomplished. The remaining step in this project is to perform the waveform synthesis with these components to demonstrate a compact optical waveform synthesizer.
