Abstract

InGaAs photodiode arrays have been developed to 'cover' the SWIR wavelength range in spectroscopy. Hybridized Si/InGaAs linear arrays have become the detector of choice for remote sensing. Device 'long' wavelength spectral performance is achieved by rearranging the photodiodes In/Ga stoichiometric ratio. However, increased long wavelength response adversely affects deice characteristics. The self-scanned InGaAs linear array mechanical and opto/electronic properties will be discussed.
