WebbThis is due to the bandgap of the molecules, which results in absorption of photons at visible and NIR wavelengths and does not absorb the lower energy SWIR wavelengths. Producers of integrated circuits use Sensors Unlimited's InGaAs cameras to inspect the quality of pure semiconductor crystals after expitaxial growth into an ingot or boule. Webb9 sep. 2008 · Spectra responses of the packaged InGaAs PIN photodiode, biased under various conditions, are plotted in Fig. 4. It was found that the measured response is almost independent of the applied bias. Such an observation indicates that internal gain in our photodiode is almost negligible due to the good crystal quality of our sample.
