ABSTRACT:
An athermal AWG module10comprises: an AWG11having waveguides partially divided to separate a chip, separated chips being connected by a compensation plate33to achieve temperature-independence; an athermal AWG chip12having a substrate and the AWG11formed on the substrate; a package13having an opening14and accommodating the athermal AWG chip12;and a cover for blocking the opening14. The athermal AWG chip12is fully covered with a gelled refractive index matching agent16that is matched in refractive index to the waveguides of the AWG11. As the gelled refractive index matching agent16is excellent in water resistance and hardly passes water, the adhesive agent for fixing the compensation plate33to the surfaces of the separated two chips is prevented from being deteriorated due to ingress of water, thereby enhancing the reliability.
