摘要： A method and device for sampling ultra-fast optical signals by generating a sampling signal comprising a train of short pulses and coupling the sampling signal together with an optical data signal to be sampled into a highly non-linear optical fibre. Four-wave mixing (FWM) occurs between the two signals resulting in a secondary signal output from the fibre consisting of pulsed components having energy proportional to the instantaneous power of points along the data signal. An analysis of this secondary signal can be carried out to create a normal trace or eye-diagram of the data signal.

摘要： An apparatus and method for generating a train of optical pulses. The apparatus comprises an optical resonant cavity (1) for confining an optical signal in the cavity to a number of modes, a modulator (3), and a control signal generator (101). The modulator comprises an interferometer arranged to cause interference of the optical signal with itself to produce an output and controllable material, such as an electro-optic crystal, arranged in a path of the optical signal, an optical property of the controllable material dependent on a control signal (3b) applied to the controllable material such that changes in the optical property alter optical signals travelling that path to affect the interference of the optical signals, and therefore the output of the modulator. The control signal generator is arranged to generate the control signal, wherein the control magnitude is an oscillating waveform arranged to cause transmission of the optical signal through the modulator to generate pulses having a pulse width shorter than a pulse width of pulses that would be generated using a sinusoidal waveform of the same frequency.

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 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.

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.
