Optical apparatus with improved center wavelength temperature stability. In an embodiment, an AWG has a plurality of slots inserted along the optical paths. The slots contain one or more compensation materials which collectively correct for an order Q temperature dependency of the AWG base material. Q>=2 or the number of compensation materials is at least 2 or both.

L'invention concerne un appareil optique présentant une stabilité de température de longueur d'onde centrale améliorée. Dans un mode de réalisation, un dispositif AWG présente une pluralité de fentes insérées le long des voies optiques. Les fentes contiennent un ou plusieurs matériaux de compensation destinés à corriger la dépendance de température d'ordre Q du matériau de base du dispositif AWG. Q>=2 ou le nombre de matériaux de compensation est d'au moins 2, ou les deux.
