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