The strict solutions of the elliptical optical waveguide are studied using the polarized light of the incident ray in cylindrical coordinate system

accurate analytical solution of the mode field distribution obtained and the mode characteristic equations derived.When light is transmitted in single mode only in the meridional plane along the long axis

single mode single polarization transmission can be achieved.Compared with the rotundity optical waveguide

the transmission constant of the elliptical optical waveguide changes very little under the same conditions for single mode transmissions.In addition

the effects of wavelength

ellipticity and relative refractive index difference on the transmission constant are briefly analyzed.
