Abstract:
A broadband polarization beam splitter/combiner based on a gradient waveguide directional coupler, comprises a gradient waveguide directional coupler, a beam combining end ( 1 ), a curved waveguide ( 5 ), a TE mode end ( 6 ) and a TM mode end ( 7 ). The coupler consists of a straight end gradient waveguide ( 2 ) and a serial end gradient waveguide ( 3 ). The trend of change of the gradient waveguide ( 2 ) is opposite to the gradient waveguide ( 3 ), and a gap is provided between the gradient waveguide ( 2 ) and the gradient waveguide ( 3 ). The beam combining end ( 1 ) is connected with one end of the gradient waveguide ( 2 ), the other end of the gradient waveguide ( 2 ) is connected with one end of the curved waveguide ( 5 ), the other end of the curved waveguide ( 5 ) is connected with the TE end ( 6 ), and the waveguide ( 3 ) is connected with the TM end ( 7 ).

Claim (Index 7):
The broadband polarization beam of  claim 1 , wherein the width of the straight end gradient waveguide ( 2 ) is increased, and the width of the serial end gradient waveguide ( 3 ) is tapered.
