Finally silicon photodiodes!

Finally, it seems that the silicon diode can be used to introduce the optical signal into the chips. And is that photodiode silicon doped developed at Harvard University.
Since silicon absorbs little infrared light, in itself it is not effective at converting information collected as light into electronic signal. However, doped with sulphur, electrons jump more easily when receiving light of this wavelength, so it is useful as photodiode.
Germanium and Indian arsenide and gallium are currently used. If you arrive on the market, silicon photodiode will be more economical. For this reason, other substances doping silicon are also intended to achieve a more effective photodiode.
