| 英文摘要 | A beam expander for providing coupling between a semiconductor optical device and an optical fiber comprises a double layer structure that may be integrated with the optical device. The first, underlying layer of the expander comprises a relatively high refractive index material (e.g., 3.34), thus providing improved coupling efficiency between the optical device and the fiber. The second, covering layer of the expander comprises a relatively low refractive index material (e.g., 3.28), for providing the large mode size desired at the fiber input. The parameters of each layer can be adjusted independently, allowing for the two criteria (coupling efficiency and mode size) to be separately optimized. |
