ABSTRACT:
A guided-wave optical wavelength duplexer fabricated as an integrated optical device, comprising input ports (2, 4) for light at different wavelengths (a.sub.1, a.sub.2) coupled to first and second waveguides (6, 8) formed on a substrate surface, the first and second waveguides having first and second coupler regions (10, 12) to enable light to be transferred from one waveguide to the other, the first and second waveguides as at (26) between the first and second coupler regions being formed as circular arcs having the same center to provide an accurately defined optical path length difference, so that light at a first wavelength (a.sub.1) is output through one output port (14) and the second component (a.sub.2) is output through another output port (16).
