Optical pulse generation based on polarisation modulation and fibre dispersion is proposed that has the ability of generating multiform optical pulse trains by applying a single electro-optic modulator and a low frequency driving signal. In the experiment, using a 10 GHz RF source, the generation of a 20 GHz time and polarisation interleaved optical pulse train, a 10 GHz single-polarisation pulse train and a 20 GHz single-polarisation pulse train is demonstrated. By using differential group delay in a polarisation maintaining fibre to realise time-division-multiplexing, the repetition rate of the pulse train can be further increased. Based on this principle, the generation of a 40 GHz time and polarisation interleaved optical pulse train, and a 40 GHz single-polarisation pulse train is successfully implemented.
