Measuring absolute spectral radiance using an Erbium Doped Fibre
Amplifier
   [PDF]

Bruno Sanguinetti, Thiago Guerreiro, Fernando Monteiro, Nicolas Gisin, Hugo Zbinden
We describe a method to measure the spectral radiance of a source in an absolute way without the need of a reference. Here we give the necessary detail to allow for the device to be reproduced from standard fiber-optic components. The device is suited for fiber-optic applications at telecom wavelengths and calibration of powermeters and spectrometers at light levels from 1nW to 1uW.
