Original Abstract Submitted
a directional coupler with reduced phase deviation is provided. the directional coupler includes a first coupler waveguide and second coupler waveguide. at least one of a spaced distance between the first coupler waveguide and the second coupler waveguide and a length of the first coupler waveguide and the second coupler waveguide selected to achieve an acceptable phase deviation and a set coupling ratio. the phase deviation is caused by a difference in loss coefficients between a first optical mode in the first coupler waveguide and a second optical mode in the second coupler waveguide.
