In order to extend the wavelength range, Si photodiode which has sensitivity to short-wavelength and InGaAs photodiode which has sensitivity to long-wavelength are stacked on the same axis. Also, to make the device more compact, we store InGaAs photodiode to the recess of Si photodiode's substrate. As a result, the height of the package could be as low as possible. (Patents have been filed.) Compared to our earlier models, the volume ratio has been reduced to 1/8.
