Various embodiments provide a PIN-photodetector configured to detect light characterized by a particular wavelength range. The photodetector includes an absorber region including a material having an absorption coefficient of greater than 10cmin the particular wavelength range. The absorber region has an absorber thickness in a direction that is substantially parallel to a detection axis of the photodetector. The photodetector further includes a collector region including a material that is substantially transparent to the particular wavelength range. The collector region has a collector thickness in the direction that is substantially parallel to the detection axis. The collector thickness is greater than the absorber thickness. The absorber region does not spatially overlap with the collector region. The photodetector is configured to operate at a bandwidth of at least 50 GHz.

Processes for continuous compositional grading for realization of low charge carrier barriers in electro-optical heterostructure semiconductor devices are provided. An example process includes forming, onto one or more semiconductor layers of an electro-optical semiconductor device, a first semiconductor layer associated with a first bandgap value and forming, onto the first semiconductor layer, a grading layer associated with a continuous compositional grading. The example method further includes forming, onto the grading layer, a second semiconductor layer associated with a second bandgap value. The second bandgap value is different than the first bandgap value.
