Fiber based ball lens
WebDec 1, 2015 · The performance of the fiber-lenses is based on the coupling efficiency between two single-mode fibers with fiber-lenses fused to their end faces. Coupling losses ranged from 0.1 to 1.6 dB for the ... WebJan 1, 2024 · We demonstrate a ball-lens based optical interface for coupling between a single mode fiber and a silicon grating coupler from the back side of a photonic integrated circuit (PIC). This allows compact packaging solutions and keeps the PIC top side accessible, e.g. for interacting with the environment in case of sensing applications.
