摘要 | Disclosed is a single mode optical waveguide fiber having a low cut off wavelength, and mode field diameter and bend resistance similar to step index single mode optical waveguide fiber designed for use at 1310 nm. By including a clad region of raised refractive index spaced apart from the core region of the single mode optical waveguide fiber, the cut off wavelength can be reduced to 850 nm. The single mode optical waveguide fiber in accord with the invention may also have a core region having a reduced refractive index on centerline surrounded by a region of higher refractive index and a clad region which is substantially uniform. The single mode optical waveguide fiber is thus ideally suited for use with the low cost, reliable VCSEL operating at 850 nm, a Fabry-Perot laser operating at 1310 nm, or a distributed feedback laser operating at 1550 nm thereby enabling low cost, easily installed, home access portions of the broadband telecommunications system. |
其他摘要 | 公开了一种单模光波导纤维,其具有低截止波长,模场直径和弯曲电阻,类似于设计用于1310nm的阶跃折射率单模光波导纤维。通过包括与单模光纤的纤芯区域间隔开的折射率升高的包层区域,截止波长可以减小到850nm。根据本发明的单模光波导纤维还可以具有在由高折射率区域围绕的中心线上具有降低的折射率的芯区域和基本均匀的包层区域。因此,单模光波导纤维非常适用于在850 nm工作的低成本,可靠的VCSEL,工作在1310 nm的法布里 - 珀罗激光器或在1550 nm工作的分布式反馈激光器,从而实现低成本,易于安装,家庭接入部分的宽带电信系统。 |
