The 1/f noise and dark current density were analysed for Sb3513_A2 photodiode. 

Attachment 1: Dark current density plot

It was observed that the dark current density has a very less difference for measurements taken across 500um, 750um and 1000um. It means that the leakage current is of low magnitude.

Attachment 2: 1/f noise at 10Hz

The 1/f noise for 500um, 750um and 1000um was plotted and 1/f noise is high for 1000um as the bias is increased. and 1/f noise is high for 500um at low bias voltages.
