Abstract

InGaAs arrays can be used to measure the magnified image of mode field profiles at 1550 nm. In order to make accurate profile measurements in this way the array needs to be fully characterised. In this paper details of the calibration of the non-linearity of the response of an InGaAs array are described. The responsivity of the array changes considerably with optical illumination unlike that of single InGaAs detectors. Without correction for this non-linearity the mode field diameter calculated from the measured mode field profile is overestimated by 15%.
