ABSTRACT:
The present invention relates to a multiplexer and/or demultiplexer optical component of the waveguide array spectrograph type, the component comprising an inlet coupler and an outlet coupler in a star configuration between which said array extends, the array having a first directed mean direction on departure of the waveguides of the array from the inlet coupler, and a second directed mean direction on arrival of the waveguides of the array at the outlet coupler, and presenting a directed general axis defined as being the axis passing through the centers of the couplers and on which a single positive direction is defined, and in which the first and second directed directions have respective directive angles measured algebraically from the general directed axis, which angles have the same sign.
