摘要
An optical detector for detecting an optical signal beam (OSB) modulated in a way that it includes an in-phase and/or a quadrature component, includes: a polarization beam splitter arranged to split the OSB into two polarized OSBs; a non-polarization beam splitter arranged to further split each of the two polarized OSBs into two split polarized OSBs; at least one birefringent element providing a phase shift, the birefringent element being arranged in a path of at least one polarized OSB and/or in a path of at least one split polarized OSB so that an in-phase and quadrature phase offset between two split polarized OSBs originating from the same polarized OSB is formed in output signal beams; and at least two detection means arranged to receive at least one output signal beam that includes a in-phase and/or quadrature component of the OSB.
