Two modes in the waveguide are excited by establishing the input light polarization at forty-five degrees so that the modes can be excited equally. After propagating through the waveguide, the two modes are forced into one polarization by a polarizing fiber so that they can interfere, and the resulting novel straight channel modulator is compact and does not require strict single mode operation since the interference is in the polarizing fiber, which is a very good mode filter.
