Abstract
We compare the results of measurements of the nonlinearity of high-power optical fiber powermeters (OFPMs) by two national metrology institutes (NMIs): the National Institute of Standards and Technology (NIST-USA) and the National Metrology Institute of Japan/National Institute of Advanced Industrial Science and Technology (NMIJ/AIST-Japan) at a wavelength of 1480nm. The nonlinearity and range discontinuity of a commercial OFPM were measured from 1mW to 500mW by use of a superposition method (both laboratories) and from 1mW to 250mW by use of a comparison method (NMIJ only). Measurement results showed largest differences of less than 1.6 parts in 103, which is within the combined expanded (k 2) uncertainty for both laboratories.
