Optical-Fiber Power Meter Comparison between NIST and KRISS



Seungkwan Kim, Keesuk Hong, Dong-Hoon Lee, David J. Livigni, Xiaoyu X. Li, John H. Lehman


We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Korea Research Institute of Standards and Science (KRISS- R.O. Korea). We report optical fiber-based power measurements at wavelengths of 1302 nm and 1546 nm. We compare the laboratories' reference standards by means of a temperature-controlled optical trap detector. Measurement results showed the largest difference of less than 2.5 parts in 103, which is within the combined standard (k=1) uncertainty for the laboratories' reference standards.
