Dark current density vs reverse bias for a set of five samples of different sizes. The inset plots the linear dependence of dark current with device area.
Spectral responsivity of a typical unbiased photodetector. The upper horizontal axis (and the shaded regions) shows the ITU- bands.
Photocurrent vs reverse bias for various optical powers incident on a device (solid lines). The input wavelength was . The dark current is graphed (dashed line) for comparison.
Typical eye diagrams (at and , respectively) from a photodetector and a PRBS generator, at an operating wavelength of . The diagrams were acquired with a sampling oscilloscope (without transimpedance amplifier).
Evaluated signal to noise ratios from the data in Fig. 3. dB units refer to voltages.
