What is the cut-off wavelength of InGaAs photodiodes ?

The long end of the spectral response of InGaAs photodiodes is limited by the bandgap energy of InGaAs which is 0.75eV at room temperature (corresponding to about 1620nm). Hence incoming light with a wavelength beyond that limit (i.e. light with a larger wavelength) will not be absorbed as InGaAs is transparent for such wavelengths. In […]

Why are you not using 175°C 2xVop for the qualification of the InGaAs PIN ?

Our HTO test condtions for the qualification are 2000h at 100°C and 2 x Vop which is typically 2 x 2.0 V. Doing so, we apply Telcordia GR-468 Issue 2 Requirements. The underlying assumption for our test conditions are: The dominant failure mechanism that will be observed for our PIN diodes is wearout failure and […]
