Abstract During this project, we demonstrated a temporal imaging system based on parametric mixing that allows simple triggering from an external clock by using a time-lens-based pump laser. We experimentally demonstrated wavelength- preserving spectral phase conjugation for compensating chromatic dispersion and self-phase modulation in optical fibers. We extended the application of photonic systems beyond characterization and demonstrated an instrument that generates complex and rapidly updateable ultrafast optical waveforms. We experimentally demonstrated a spectral magnifier using an imaging system with two time-lenses based on four-wave mixing in a Si nanowaveguide. We demonstrated a single-shot technique for optical sampling based on temporal magnification using a silicon-chip time lens. We demonstrated the largest reported temporal magnification factor yet achieved (>500) and applied this technique to perform 1.3 TS/s single-shot sampling of ultrafast waveforms and to 80-Gb/s performance monitoring. Using time-to-frequency conversion via the nonlinear process of four-wave mixing on a silicon chip, we demonstrated a waveform measurement technology within a silicon-photonic platform. We measured optical waveforms with 220-fs resolution over lengths greater than 100 ps, which represent the largest record-length-to-resolution ratio (>450) of any single-shot-capable picosecond waveform measurement technique.
