Abstract: In known coherent optical receivers with two detectors, optical 90 DEG hydrids have a throughput </=25%. Theoretical analysis shows that a higher throughput, up to a maximum of approximately 29.3%, is possible. The invention provides such a 90 DEG  hybrid (30) of the polarisation type. In an optical hybrid (3) having a structure known per se, i.e. polarisation controllers (38, 39) at the inputs (40 and 41) of a power coupler (42), and polarisers (45, 46) at the outputs (43 and 44) thereof, the polarisation controllers and the polarisers are put into such positions, that the points on the Poincaré sphere, which correspond to those positions, comply with two conditions which guarantee a 90 DEG  phase difference and the higher throughput. For example, the positions correspond to points which represent positions in which the polarisation controllers produce mutually opposite elliptical polarisations at an angle  alpha  and the polarisers are placed linearly at angles  alpha  and - alpha , and a APPROX 32.8 DEG . <IMAGE>
