Degradation of the frequency response of photodiodes in measurements of strong optical signals

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...

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. En este trabajo se presentan mediciones que revelan cambios en la respuesta en frecuencia de un fotodetector tipo PIN debida al cambio en la intensidad de la luz que llega al detector. En particular, se observan dos efectos a altos niveles de iluminacion: el ancho de banda del detector disminuye y se modifica su respuesta de fase. Para bajas intensidades el ancho de banda sigue una ley de potencias con exponente -1 con la corriente media del fotodetector, pero, para alta iluminacion, el exponente tiende a -0,5. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/23 10.37537/rev.elektron.1.2.23.2017 spa FIUBA https://elektron.fi.uba.ar/elektron/article/view/23/31 https://elektron.fi.uba.ar/elektron/article/view/23/158 Derechos de autor 2017 Eduardo Omar Acosta Elektron Journal; Vol. 1 No. 2 (2017); 75-78 Revista Elektron; Vol. 1 Núm. 2 (2017); 75-78 Revista Elektron; v. 1 n. 2 (2017); 75-78 2525-0159 2525-0159 PIN photodiode Detector bandwidth Phase Response fotodectector respuesta en frecuencia diodo PIN Degradation of the frequency response of photodiodes in measurements of strong optical signals Degradación de la respuesta en frecuencia de fotodiodos en mediciones de señales ópticas intensas info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=23_oai
