摘要： The invention concerns a method for characterizing mode group properties of multimodal light traveling through an optical component, comprising: providing a Mode Group Separating optical fiber in an optical path between a light source and said optical component; launching reference pulses of light with a wavelength λt from said light source through said Mode Group Separating optical fiber into said optical component at discrete intervals between a core center and a core radius of said fiber. The Mode Group Separating optical fiber is a multimode fiber with an α-profile graded index core with an α-value chosen such that said fiber satisfies the following criterion at the wavelength λt:  Δτ  · L Δ   T REF > 4 where: Δτ is a time delay difference between consecutive mode groups; L is a length of said fiber; ΔTREF is a Full Width at Quarter Maximum of said reference pulses.

摘要： The invention relates to a method of measuring time delays with respect to differential mode delay of a multi-mode fiber or a few-mode fiber for at least two different wavelengths. The time delays for each wavelength are measured before the single mode fiber is translated to a next radial offset.

摘要： A multimode optical fiber includes a central core surrounded by an outer cladding. The central core has a graded-index profile with respect to the outer cladding and an outer radius r1 of between about 30 microns and 50 microns (e.g., between about 35 microns and 45 microns). The optical fiber also includes an inner cladding positioned between the central core and the outer cladding, and a depressed trench positioned between the inner cladding and the outer cladding. The multimode optical fiber exhibits reduced bending losses.
