A double-channel lossy-dielectric waveguide, having its propagation characteristics controlled by the action of light, is analyzed here. The light is incident on a semiconductor material that constitutes the inner channel of the waveguide structure, generating a plasma. The analysis of the problem i

## Abstract A fairly rigorous analytical treatment of the power characteristics of dielectric optical waveguides with Piet Hein coreβcross sectional geometry is presented in this paper. This kind of waveguide structure would be advantageous owing to the absence of corners, which are found in rectan
sion line by almost 2 β and 0.5α0.75 cmrns, respectively. Because the SiO layer has a significantly lower dielectric 2 constant than that of GaAs, its inclusion will result in a smaller capacitance per unit length of the CPS slow-wave electrodes. This results in an increase in the phase velocity of
