What is the cut-off wavelength of GaAs photodiodes ?
The long end of the spectral response of GaAs photodiodes is limited by the bandgap energy of GaAs which is 1.42eV (corresponding to about 870nm). Hence incoming light with a wavelength beyond that limit (i.e. light with a larger wavelength) will not be absorbed as GaAs is transparent for such wavelengths. In the wavelength region […]
