Background-free collinear autocorrelation and frequency-resolved optical gating using mode multiplexing and demultiplexing in aperiodically poled lithium niobate waveguides.
We use mode multiplexing and demultiplexing in apodized aperiodically poled lithium niobate waveguides to enable characterization of picosecond optical pulses in a collinear but background-free way using autocorrelation and second-harmonic frequency-resolved optical gating.
