Abstract
An all-optical sampling device using four-wave mixing in third-order optically nonlinear materials is described. The four-wave mixing based sampler comprises a waveguide combiner, which adds a gate optical signal to a signal of interest to be sampled. In a four-wave mixing region, a sampled signal at the output optical frequency is produced. All of the optical signals are sent to a passive optical filter, which preferentially discards the gate and signal optical frequencies, but preserves the sampled signal at the output optical frequency. The sampled signal at the output optical frequency can be observed, displayed, recorded or otherwise manipulated.
