Abstract :
We demonstrate temporal measurements of sub-picosecond optical pulses via time-to-frequency conversion in a 45-cm-long CMOS compatible high-index glass spiral waveguide. The measurements are based on efficient four-wave mixing in the C-band, using around 1 W of peak pump power. We achieve a resolution of 400 fs over a time window of 100 ps, representing a time-bandwidth product >; 250.
