Abstract :
A calorimeter for optical fiber power measurement is developed. It has a compensative absorber to stabilize environmental disturbance, and two types of adapters for optical fibers and light beams. The uncertainty in measurements of 1-mW and 10-μW optical fiber power was evaluated as ±0.18% and ±0.45% respectively, expressed as two standard deviations. The calibration uncertainty of an optical fiber power meter using the calorimeter as a primary standard is reduced by more than one half compared to that of the conventional method using a laser beam calorimeter and photodiode-type transfer standard
