There has been significant progress on the development of Type II superlattice detectors in the past 15 years. As we have progressed in advanced heterostructure engineering of the devices, it has also provided insight into some of the challenges associated with the superlattices. In this talk, I will discuss some of our recent results on unipolar barrier detectors. I will also discuss some of the fundamental challenges that need to be addressed for the superlattice detectors such as vertical transport and surface passivation. I will also present some interesting problems including superlattice based avalanche photodiodes and the growth of metamorphic InAsSb absorbers.
