    Abstract: A fiber optic waveguide is provided. The fiber optic waveguide includes a core region, and a cladding region surrounding the core region. The cladding region includes an inner cladding region and an outer cladding region. The inner cladding region has a lattice of ring structures. The core region is formed from a high index material and the cladding region is formed from materials producing an effective refractive index lower than the refractive index of the core region.

    Abstract: Concepts of the present disclosure may be employed to optimize optical pumping and ensure high modal gain in the active region of an optically pumped laser source by establishing an optical coupling gap such that the pump waveguide mode field overlaps the active gain region associated with the signal waveguide. The optical coupling gap is tailored to be sufficiently large to ensure that a significant active gain region length is required for absorption and sufficiently small to ensure that the pump waveguide mode field P overlaps the active gain region. In accordance with one embodiment of the present disclosure, the pump waveguide core is displaced from the signal waveguide core by an optical coupling gap g in a lateral direction that is approximately perpendicular to the optical pumping axis. A decayed intensity portion of the pump waveguide mode field extends into the active gain region to optically pump the active gain region and form an optical signal propagating along the longitudinal optical signal axis of the signal waveguide core.

    Abstract translation: 可以采用本公开的概念来优化光泵浦，并且通过建立光耦合间隙来确保光泵浦激光源的有源区域中的高模态增益，使得泵波导模场与与信号波导相关联的有源增益区域重叠 。 光学耦合间隙被定制为足够大以确保吸收所需的显着的有源增益区域长度并且足够小以确保泵浦波导模式场P与有源增益区域重叠。 根据本公开的一个实施例，泵浦波导芯通过大致垂直于光泵浦轴的横向方向上的光耦合间隙g从信号波导芯移位。 泵浦波导模场的衰减强度部分延伸到有源增益区域以光学泵浦有源增益区域并形成沿着信号波导芯的纵向光信号轴传播的光信号。
