✦ Synopsis

of the TE and TM modes in the semiconducting walls as 0 0

the differential attenuationrabsorption of the modes in the cladded portion basically depends on the boundary condition Ž . Ž . of the listed equations 1 ᎐ 4 and the complex dielectric constant of the clad, and hence the material. This leads to a variation in the clad length among the metals, and also in semiconductors.

CONCLUSION

This study indicates that the metal clads can be used to cut off the TM mode, whereas the dielectric clads can be used 0 to cut off the TE mode. This cutoff length can be used to 0 calculate the conductivities of the material at optical frequency. These cladded waveguides can also be used as a sensor in a particular polarized mode.
