Abstract
An optical device, and a method of producing the device, are disclosed. The device comprises a substrate and an optical waveguide component affixed to the substrate with a glass frit fusion seal formed and locked within a recessed void in the substrate, the glass frit fusion seal being the fused product of a low melting glass frit. The recessed void in the substrate includes a region for receiving the optical waveguide component and an intersecting region that secures the placement of the glass frit fusion seal. The optical waveguide component is affixed to the substrate in order to control temperature varying optical properties of the component.
