Author Affiliations +
Coherent nonlinear resonances due to extended and localized excitons in CdSe and CdSeS1_ are investigated by picosecond time resolved degenerate four-wave mixing. Large nonlinear coefficients (X(31O_9cm2/V2) are found, with coherence times in the picosecond range. Preliminary results on picosecond optical switching in CdSe are presented, and the possibility of a purely coherent optical switching with picosecond response time is discussed.
