Abstract
Semiconductor devices comprising a semiconductor edge filter, a first light absorbing region overlying the semiconductor edge filter and a second light absorbing region underlying the semiconductor edge filter are disclosed. The semiconductor edge filter has a high reflectivity over a first wavelength range absorbed by the overlying light absorbing region and a high transmission over a second wavelength range absorbed by the underlying light absorbing region.
