Optical fiber wavelength division multiplexer based on two-mode interference
An optical fiber wavelength division multiplexer based on two-mode interference has been analyzed. A theoretical model based on solution of the wave equation for a two-mode optical waveguide by computing their propagation characteristics is used. In addition, the coupled power between these two modes has been investigated. The dependence of the coupled power on the wavelength, the core radius and the refractive index is studied. The variations of the beat length against the core radius and the operating wavelength, the variations of the crosstalk against the length of the device and the operating wavelength have been also investigated. The results show that the variations of the wavelength change the coupled power between the two modes from 0% to 100%, and show that this type of model can be exploited as an optical wavelength division multiplexer (WDM) for single-mode optical fiber systems.
