Two‐photon coherent control of dark orthoexcitons in Cu2O
Kosuke Yoshioka, Makoto Kuwata‐Gonokami
Abstract
Abstract We investigate experimentally the two‐photon coherence exhibited by optically forbidden exciton states in the bulk semiconductor Cu2O. Two‐photon coherent control is achieved by using phase‐locked optical pulse pairs. Very long dephasing times and a fine energy splittings of the order of µ‐eV are observed.
