title: Direct measurement of the effective refractive indices of GaAs/AIGaAs slab waveguides: a new technique.
abstract: A new method is presented for accurately and nondestructively measuring the effective refractive indices of GaAs slab waveguides. The experimental setup is extremely simple. This method is particularly applicable for buried waveguides and high refractive index waveguides that cannot be measured by prism couplers. It is also suitable for glass and LiNbO(3) waveguides.
