Wavelength Band UV-SWIR, 400-2150 nm; Scalar FEM Numerical Engine; Solution in Seconds; ASCII Fiber Profile Input & Data Output; System Requirements 64-bit MS Windows Based on fiber refractive index profile data, Interfiber Analysis’ “2D Mode Solver” software package computes guided modes and mode properties, fiber bending/coiling effects, as well as mode coupling at splices. The software tool can analyze either 1-dimensional or 2-dimensional fiber index data so it can quantify the impact of any asymmetries in the fiber index profile. With this tool, you can: Compute 2-dimensional fiber modefields and mode properties Predict mode coupling at fiber splices Model fiber bending effects Quantify impact of index profile asymmetries Determine overlap between modes and cores Analyze fiber, preform, or synthetic index profiles These capabilities make the software particularly useful for customers working with high-power optical fibers. It is not only useful for existing IFA-100 users (who can use it to compute modes based on their IFA-100 data,) but also for those who use other equipment as it can be applied to fiber index data from other measurement devices (including preform profilers). This very attractively priced software tool runs on MS Windows 64-bit computers, and unlike other competing software packages, we offer multiple licenses at the customer location for the price of a single purchase.

500 to 1000 nm; Refractive Index Accuracy ±0.0001; Spatial Resolution 500 nm; Fiber Type SM, MM, PM, Other; Fiber Diameter 40 to 400 µm Interfiber Analysis’ IFA-100 multi-wavelength interferometric optical fiber analyzer can measure the refractive index profile of an optical fiber without the need for a cleave at wavelengths from 375 to 2000 nm. By scanning the fiber from the side, the IFA-100 unit allows for scanning and measuring the optical refractive index profile (RIP) along the fiber’s length with sub-micron spatial resolution. The measurement is independent of cumbersome fiber preparation like cleaving and allows for measuring the evolution of the refractive index profile over a given length of fiber. The equipment uses a broadband light source and can determine the refractive index profile at any wavelength between visible and near infrared. The refractive index or index of refraction (IOR) is a property of any material. For optically transmitting materials, such as for fibers and waveguides, it is reflected in the reduced speed of light when travelling through any media other than vacuum. Fibers and waveguides use a distribution of the IOR within their cross section to guide and reflect light, and knowledge of this distribution allows many other critical performance parameters to be calculated, such as mode fields, group and phase propagation constants and fiber dispersion.

Measurement of 1-D, 2-D, 3-D Fiber Refractive Index Profiles; No Costly Instrument Purchase; 500 to 1000 nm; Refractive Index Accuracy ±0.0001; Spatial Resolution 500 nm Based on Interfiber Analysis’ IFA-100 multi-wavelength interferometric optical fiber analyzer, AMS Technologies offers refractive index measurement services for product development, incoming inspection and forensic analysis on optical fibers. At our testing facility in Munich we can secure quick sample turnaround and offer confidentiality of measurement results. The refractive index profile allows determination of key transmission parameters like chromatic dispersion, mode field diameter, bandwidth, birefringence and polarization mode dispersion (PMD). Line plots and tomography scans: The measurements can be taken in one dimension giving a line plot of the refractive index at any given cross section of the fiber. This measurement assumes the fiber to be symmetrical, and symmetrical geometry is assumed for the computation of the refractive index profile. For the two-dimensional measurements, several lower-dimensional projections are combined to form a full surface profile of the refractive index. This computer tomography based approach does not take assumptions for the fibers being symmetric. Environmental testing solution: The interferometry measurement technique used in the setup does not require external calibration. Measurements can be done with fiber diameters from 40 to 400 µm within a measurement wavelength from 500 to 1000 nm. Fiber material can be silica glass, non-silica glass or plastic. The accuracy of index of refraction is ±0.0001, accuracy of stress measurement is ±5 MPa.
