Abstract
A 90 degrees hybrid which consists of a beam combiner and two polarisation separators is proposed for optical preprocessing in Costas homodyne receivers. It utilises all the available optical power. The power distribution between the inphase and the quadrature arm can be arbitrarily adjusted.
