| 摘要 |
The invention concerns an integrated optical device allowing for separation of the polarized components of a guided electromagnetic field which, in order to obtain separation, comprises a coupler comprising a first and a second electromagnetic wave guide structure, the core of each structure being spaced by a predetermined interval so as to enable the energy of one of the structures to be coupled to the other structure, these structures admitting guided modes and having different effective indices for a first polarized component of the electromagnetic field and equal for a second polarized component of said field, the interval between these cores being constant over a predetermined distance (L) at the end of which the energy is totally transferred for the second polarized component, this interval increasing at the end of this distance (L) so as to be able to recover on each of these structures one of the polarized components of the field.
