A polarisation control method includes the steps of feeding an optical input signal to a first polarisation transformation block for providing a corresponding first optical output signal; feeding the first optical output signal to a second for providing a corresponding second output signal; providing to the blocks, regulating signals which are variable within limited time intervals and adapted to induce the blocks to assume a configuration wherein the second block is in an active state and the first block is in a reset state in order to carry out a rewind operation wherein the corresponding regulating signal is induced to assume a value within the corresponding limited interval.
