摘要： The present invention relates to an optical sampler, to a systemincluding such a sampler, and to a method of sampling an optical signal comprising a pattern having a frequency. The method comprises providing the optical signal to a nonlinear medium, generating an optical sampling signal comprising a series of optical pulses, providing the optical sampling signal to the nonlinear medium to interact with the optical signal and thereby induce a nonlinear effect; and obtaining a sample result by making a measurement indicative of said induced nonlinear effect. The step of generating the optical sampling signal comprises controlling the frequency of said series ofoptical pulses using a controlsignal dependent upon the difference between a predetermined reference signal frequency and a predetermined function of the frequency of the pattern.

摘要： A method (100) for dual polarisation optical transmission is disclosed. The method comprises splitting a continuous wave light source into first and second sub-channels (110), optically modulating each sub-channel with a data signal (120), and superimposing a first pilot tone onto the first optically modulated sub-channel and a second pilot tone, different from the first pilot tone, onto the second optically modulated sub-channel (130). The method further comprises polarisation multiplexing the first and second sub-channels to form a polarisation multiplexed signal (140), in which the first and second sub-channels have orthogonal states of polarisation, and transmitting the polarisation multiplexed signal (150).

摘要： An optical transmission method (10) comprising steps of receiving (12) a communication signal comprising symbols for transmission. The method comprises performing (16) linear amplitude modulation of an optical carrier with the communication signal to generate an amplitude modulated optical carrier. The method comprises performing low-pass filtering (14) to reduce a bandwidth of the symbols to less than a Nyquist bandwidth of the symbols. The method comprises transmitting (18) the amplitude modulated optical carrier. The method further comprises receiving (20) the amplitude modulated optical carrier following transmission and performing direct detection of the received amplitude modulated optical carrier to generate a received electrical signal; and determining (22) received symbols from the received electrical signal using an indication of a nonlinear impulse response of the direct detection.
