An optical transmitter, an optical receiver and an optical transmission method are used to solve the problem of high demultiplexing complexity existing in the prior art. The optical transmitter includes an optical signal generator, n spread spectrum generators, n pair data modulators and combiners; the optical signal generator generates n single wavelength optical carriers; the I spread spectrum processor spreads the spectrum of the I optical carrier generated by the optical signal generator to obtain the spread spectrum optical signal with two sub carriers, and divides the spread spectrum optical signal into the first optical signal and the second optical signal, and For the second optical signal, delay processing is carried out to obtain the third optical signal; for the data modulator, modulation processing is carried out for the first optical signal and the third optical signal to obtain a pair of modulated optical signals, and a pair of modulated optical signals are respectively transmitted to the combiner; a pair of modulated optical signals arriving at the combiner differ by 1 / 4f in time domain
