Abstract
Abstract:A calibration system for optical fiber laser sources has been developed at the Government of the Hong Kong Special Administrative Region Standards and Calibration Laboratory (SCL). The measurements of wavelength, output power level and output power stability of optical fiber laser sources fitted with fiber channel/angled physical contact (FC/APC) connectors are detailed. The wavelength is directly measured by the laboratory wavelength meter. The standard measurement uncertainty obtainable by this calibration method is less than 1 picometer (pm). The output power is the summation of the measured power by the laboratory's electrically calibrated pyroelectric radiometer (ECPR), and the insertion loss between the source and the ECPR with a standard measurement uncertainty of about 3.7 %. The output power stability is evaluated by measuring the maximum and minimum fluctuation of the measured optical power using the laboratory ECPR which has three significant digits of resolution.
