K1 Electrónica K1 Electronics AB We describe the design, characterization, and calibration of a high-power and high-accuracy transfer standard for optical power measurements in fibers based on an integrating sphere radiometer working from -50 to +30 dBm. The integrating sphere radiometer has been calibrated in the spectral range 1250-1650 nm by use of an electrically calibrated pyroelectric radiometer and four tunable laser diodes. The total uncertainty obtained is less than ±0.8% for these wavelength and power ranges PB Optical Society of America SN 1559-128X YR 2006 FD 2006-01-20 LK http://hdl.handle.net/10017/28617 UL http://hdl.handle.net/10017/28617 LA eng NO Ministerio de Educación y Ciencia DS MINDS@UW RD 19-abr-2024
