We discuss propagation effects that occur in semiconductors at frequencies above the absorption edge, including inhibition of linear absorption using phase-locked harmonic pulses, negative refraction, anomalous momentum states predicted in negative-index materials, and sub-wavelength imaging. These phenomena may help pave the way to new practical uses of semiconductors, in regimes that are currently thought to be uninteresting and mostly inaccessible.
