Degradación de la respuesta en frecuencia de fotodiodos en mediciones de señales ópticas intensas
In this paper we present measurements that reveal changes in the frequency response of a PIN-type photodetector with the increase of the intensity of the light reaching the detector. In particular, two effects are observed at high illumination levels: the bandwidth of the detector decreases and the...

| Sumario: | In this paper we present measurements that reveal changes in the frequency response of a PIN-type photodetector with the increase of the intensity of the light reaching the detector. In particular, two effects are observed at high illumination levels: the bandwidth of the detector decreases and the phase response is modified. For low intensities the bandwidth follows a power law with exponent -1 with the average current of the photodetector, but at high illumination the exponent tends to -0.5. |
