- Consider a dielectric slab waveguide that has a thin GaAs layer of thickness 0.25 m between two AlGaAs layers. The refractive index of GaAs is 3.6 and that of the AlGaAs layers is 3.4. What is the cutoff wavelength beyond which only a single mode can propagate in the waveguide, assuming that the refractive index does not vary greatly with the wavelength?
