A novel four‐branch single‐mode wide‐angle power divider, consisting of a symmetric Y‐branch waveguide with a phase front retarder around the junction and a central V‐shaped two‐branch waveguide located a coupling gap apart, is proposed. Low loss, large angle, and uniform output power distribution can be achieved by adjusting the gap between Y‐branch and V‐shaped two‐branch waveguides. Moreover, the proposed power divider can be used in wide‐bandwidth wavelength‐division‐multiplexing (WDM) systems. Also, the effect on the power‐dividing ratio is insensitive to fabrication tolerance. © 2003 Wiley Periodicals, Inc.
