ABSTRACT:
An optical waveguide device based on the self-imaging (Talbot) effect is closed. An induced mode index difference between the device's multimode propagation (MMP) region and its surrounding host region forms a total internal reflection (TIR) interface. A pair of TIR interfaces result in lateral waveguide mode confinement and self-imaging formation. Also disclosed is an improved method of manufacturing the waveguide device.
