摘要： An optical pulse generator comprises a source of polarised optical pulses each having a first frequency spectrum, a length of non-polarisation maintaining highly nonlinear fibre (HNLF) connected to the source, and a polarisation rotator connected to the HNLF. An optical pulse output from the source is guided along the HNLF to the polarisation rotator, whereat the polarisation of the pulse is rotated, and wherein the rotated pulse is re-input to the HNLF, guided along the HNLF, and output from the HNLF as a modified optical pulse. The modified optical pulse has a second frequency spectrumthat is broader than the first frequency spectrum due to interaction between the optical pulse with the HNLF, and wherein the modified optical pulse is substantially polarised.

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 froma relatively high power state to a relatively low power state has an associated falling edge transition time, and switching the flip-flop output froma 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 transitiontimes of boththe 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.
