A cavity between the bridge waveguide structure and the chip is at least partially filled with an adhesive resin and a filler material having a coefficient of thermal expansion (CTE) less than that of the adhesive resin. The filler material may include filler particles dispersed throughout the adhesive resin, or a discrete layer of material separate from the adhesive resin. The composite adhesive material filling the cavity has an effective coefficient of thermal expansion less than the coefficient of thermal expansion of conventional adhesive resins. This lower effective CTE improves the survivability of the overlying bridge waveguide structure following thermal cycling of the optical system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fiber alignment to photonics chip","description":"An optical system includes a photonics chip, a bridge waveguide structure formed on the chip, and an optical fiber disposed over the chip and optically aligned with the bridge waveguide structure.
