Abstract:
1. An optical apparatus comprising: a device substrate with at least one optical component thereon and with a fiber groove thereon; a segment of optical fiber engaged with the fiber groove, the fiber groove positioning a first end of the fiber segment engaged therewith for optical coupling with at least one optical component on the substrate; a fiber retainer positioned over the fiber segment and engaged therewith so as to maintain the fiber segment in engagement with the fiber groove; and adhesive means for securing the fiber retainer to the device substrate, the adhesive means (a) forming at least one retaining member that at least partially fills at least one recessed region formed on the device substrate, that recessed region being spatially separate from the fiber groove, and (b) forming at least one retaining member that at least partially fills at least one recessed region formed on the fiber retainer, that recessed region being spatially separate from an area of the fiber retainer engaged with the fiber, wherein an opening of each recessed region is smaller in at least one transverse dimension than a deeper portion of that recessed region, so that at least a portion of each retaining member is larger in at least one transverse dimension than an opening of the corresponding recessed region.
