Area of Science:

Metrology and Measurement Science
Optical Engineering
National Metrology Institutes

Background:

Accurate optical power measurement is critical for telecommunications and photonics.
International comparisons ensure consistency of measurement standards.
National Institute of Standards and Technology (NIST-USA) and Korea Research Institute of Standards and Science (KRISS-R.O. Korea) are leading metrology institutes.

Purpose of the Study:

To compare the national optical fiber power measurement reference standards of NIST-USA and KRISS-R.O. Korea.
To assess the agreement between the two institutes' standards at specific wavelengths.
To validate the accuracy and comparability of optical power measurements internationally.

Main Methods:

Utilized a temperature-controlled optical trap detector for precise measurements.
Conducted intercomparison of reference standards at 1302 nm and 1546 nm wavelengths.
Analyzed measurement results to determine the difference between the laboratories' standards.

Main Results:

The largest difference observed between NIST-USA and KRISS-R.O. Korea reference standards was less than 2.5 parts in 10^3.
This difference was within the combined standard uncertainty (k=1) of the measurements.
Demonstrated high agreement between the two national metrology institutes' standards.

Conclusions:

The reference standards for optical fiber power measurements at NIST-USA and KRISS-R.O. Korea are in excellent agreement.
The intercomparison validates the reliability of optical power measurements conducted by both institutes.
This supports global consistency in optical metrology.
