A new structure for suppressing the relative intensity noise (RIN) from an optical source is presented. It is based on an integrated dual-polarisation dual-parallel modulator and a balanced detector. It only requires a single fibre connected between the transmitter and the receiver whereas two fibres are required in the conventional dual-output modulator based RIN suppression structure. Experimental results demonstrate RIN suppression of >10 dB 10 dB over 1-16 GHz frequency range with and without RF signal modulation.
