| 摘要 | An optical coupling mount for use in coupling light between a semiconductor waveguide device (2, 42) and an optical fibre comprises a silica based spot size converter (3, 43) located on an optical bench (1, 40) with a trench (8, 47) and grooves (9, 48), whereby the semiconductor device (2, 42) can be positioned in close alignment with the spot size converter (3). The spot size converter (3) comprises a tapered upper waveguide (4, 45) located above a non-tapered lower waveguide (6, 44). The dimensions of the spot size converter (3) are such that a semiconductor device emitting a small, astigmatic optical beam can be efficiently coupled to a single mode fibre requiring a larger, concentric beam. |
| 其他摘要 | 用于在半导体波导器件（2,42）和光纤之间耦合光的光学耦合安装件包括位于具有沟槽的光具座（1,40）上的基于二氧化硅的光斑尺寸转换器（3,43）。 47）和凹槽（9,48），由此半导体器件（2,42）可以定位成与光斑尺寸转换器（3）紧密对准。光斑尺寸转换器（3）包括位于非锥形下部波导（6,44）上方的锥形上部波导（4,45）。光斑尺寸转换器（3）的尺寸使得发射小的像散光束的半导体器件可以有效地耦合到需要更大的同心光束的单模光纤。 |
