Room-temperature waveguide properties have been studied experimentally in \(\mathrm{ZnSe}\) based multiple-quantum-well laser structures. The spectra of waveguide transmission show distinct spectral features associated witb heavy- and light-hole quantum well excitons. Refractive index dispersion in
