ABSTRACT:
An optical sampler with high temporal resolution comprises a TOAD device with a loop optical path at the inlet of which is input an optical signal to be sampled and along which path is arranged a point of input of an optical control signal produced by a source and appropriately delayed by a delay line to change on command the temporal position of the TOAD transmittance window compared to the signal to be sampled. In the loop there is also a nonlinear device. The sampler includes a controller to command the delay line to move step by step the transmittance window and make it run on the signal to be sampled. The mean power transmitted at the TOAD output is measured for each window position and a derivative on the mean powers found for each window position is performed, thus finding samples representing the optical signal.
