Propagation-Induced Escape from Adiabatic Following in a Semiconductor

Coherent pulse propagation, including self-induced transparency and pulse breakup, is well-known in atomic media. Pulse propagation and optical soliton formation have been studied extensively in optical fibers. However, investigations of coherent pulse propagation effects in semiconductors are very rare. We have reported a combined experimental and theoretical study showing coherent pulse breakup in a semiconductor waveguide for photon energies below the lowest (ls) exciton resonance.
