Se-ZnSe strained layer superlattice with waveguide structure was prepared successfully on GaAs substrate by MOCVD. The radiative recombination of
n
=1 heavy and light hole excitons is observed in photoluminescence spectra at 77 K. The lasing oscillation modes in a F-P cavity with waveguide structure are observed at 77 K under optical pumping operation. It is found that the different modes have different threasholds. The narrower the half width of the time delay curve is
