摘要： In various embodiments, a semi-guiding optical fiber includes a core having a first refractive index and a high aspect ratio elongated cross-section along a slow axis direction. First and second signal claddings having a second refractive index sandwich the core. A third cladding having a third refractive index substantially surrounds at least side edges of the core. The first refractive index of the core, the third refractive index of the third cladding, and/or the second refractive index of the first and second signal claddings, are selected so as to maximize a differential loss between a lowest order mode propagating in the optical fiber and next order modes so as to discriminate in favor of the lowest order mode and against the next order modes. In another embodiment, a method for mode control in a semi-guiding medium includes controlling either the first refractive index of the core, the second refractive index of the first and second signal claddings, and/or the third refractive index of the third cladding, to maximize a differential loss between a lowest order mode propagating in the optical fiber and next order modes so as to discriminate in favor of the lowest order mode and against the next order modes.

摘要： In various embodiments, an optical element, e.g., an optical fiber, may be configured to compensate for thermal lensing. For example, thermal lensing may be caused by light power dissipation within an optical fiber, which may include a fiber core that guides amplified light along the longitudinal dimension of the fiber core. Thermal lensing from a thermally induced change in material refractive index as a function of position along dimensions perpendicular to the fiber's longitudinal dimension may be at least partially compensated or offset when light is guided by the fiber core by a designed-in effective refractive index profile selected such that the designed-in material refractive index of the fiber core changes as a function of transverse position within the fiber core, or by selection of a favorable cross-sectional core shape in a plane perpendicular to the longitudinal dimension of the fiber core.
