摘要： An optical flip-flop comprises first (102) and second (104) flip-flop elements arranged to respectively provide first (output 1) and second (output 3) optical outputs. Each output is in one of a plurality of states, wherein switching the output from a relatively high power state to a relatively low power state has an associated falling edge transition time, and switching the output from a relatively low power state to a relatively high power state has an associated rising edge transition time. The rising edge transition time is greater than the falling edge transition time. The optical flip-flop also comprises a processor (106) arranged to process the first and second outputs to provide an optical flip-flop output, being one of a plurality of state outputs, wherein switching the flip-flop output from a relatively high power state to a relatively low power state has an associated falling edge transition time, and switching the flip-flop output from a relatively low power state to a relatively high power state has an associated rising edge transition time. The processor is arranged to process the first and second outputs such that both the falling edge transition time and the rising edge transition time of the flip-flop output are independent of the rising edge transition times of both the first and second flip-flop elements. The invention also provides a method of operating the flip-flop, an optical switching arrangement and an optical switching method.

摘要： 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.

An SOA (11) element receives such input signals to be piloted thereby in saturation and its output is connected to at least one optical filter (14, 15, 16) that filters components of signals output from the SOA and which represent a desired logical result of the signals input at the gate so that at the output (13) of the filter there is an optical signal as the result of the desired logical operation.
